Description of the Invention: [Technical Field] The present invention relates to a two-wire type load control device that is connected in series between a load of an AC power source and a lighting device. [Prior Art] Previously, a load control device for a lighting device using a contactless switch element such as a triac or a thyristor has been put to practical use. From the viewpoint of saving wiring, the load control devices are generally two-wire wiring and are connected in series between the AC power source and the load. For such a load control device connected in series between the AC power source and the load, the problem is how to protect the circuit power of the circuit itself. The load control device 50 of the first prior art shown in FIG. 44 is connected in series between the AC power supply 2 and the load 3, and the main opening/closing unit 51, the rectifying unit 52, and the control unit 53 supply a stable power supply to The second power supply unit 55 that supplies electric power to the first power supply φ unit 54 in a state where power supply to the load 3 is stopped is supplied to the first power supply unit 54 when power is supplied to the load 3. The third power supply unit 56 for electric power and the auxiliary opening and closing unit 57 that receives a minute current in the load current are configured. The main switching element 51a of the main opening and closing portion 51 is constituted by a bidirectional triode. When the load control device 50 that is not supplying power to the load 3 is disconnected, the voltage applied from the AC power supply 2 to the load control device 50 is supplied to the second power supply unit 55 via the rectifying unit 52. The second power supply unit 55 is a constant voltage circuit composed of a resistor and a Zener diode. At this time, it is set that the current flowing through the load 3 is 2010. The current is a small current 'the degree does not cause the load 3 to malfunction, the current consumption of the control unit 53 is small' and the second power supply unit 55 maintains a high impedance (impedance) ). On the other hand, when the load control device 50 is turned on, the power supply to the load 3 is turned on, the third power supply unit 56 is turned on according to the control signal from the control unit 53, and the impedance of the load control device 50 is lowered. The amount of current flowing through the load 3 increases, and the current flowing through the third power supply unit 56 also flows to the first power supply unit 54, and the snubber capacitor (buffercapacit〇r) 54a starts charging. If the charging voltage of the snubber capacitor 54a is higher than the predetermined When the limit value is further south, the Zener diode 56a constituting the third power supply unit 56 is broken and the current starts to flow, whereby the current flows to the gate of the auxiliary opening and closing portion 57 so that the auxiliary opening and closing portion 57 In the on state, the current flowing from the rectifying unit 52 to the third power supply unit 56 is turned to the auxiliary opening and closing unit 57, and further flows to the gate of the main switching element 51a of the main opening and closing unit 51, so that the main opening and closing unit 51 is turned on ( In the closed state. Therefore, almost all of the electric power is supplied to the load 3. If the main opening and closing portion 51 is temporarily turned on (closed state), the current continues to flow, but when the alternating current reaches the zero-crossing point, the main switching element 51a When the main opening and closing portion 51 is rendered non-conductive (open state), the current is again extinguished from the rectifying unit 52 to the first portion via the third power supply unit 56. The power supply unit 54 performs the operation of the own circuit power supply for ensuring the load control device 5A. That is, the operation of securing the own circuit power supply of the load control device 5A is repeated every 1/2 cycle of the AC power supply, and the auxiliary opening and closing unit 57 is provided. The conduction is performed by the conduction operation of the opening and closing portion 51. 201034517

Further, a second switch portion having a larger on-resistance than the main switching element (first switch portion) is provided, and the first switch portion is turned on after the second switch portion is turned on. However, in the third prior example as described above, the number of switching elements is increased, the circuit configuration becomes complicated, and the control of the timing at which the switch is turned on becomes complicated. In addition, in recent years, the electric-lamp type fluorescent lamp has been widely used, and the main switching element 61a of the main opening/closing unit 61 is a transistor, as in the load control device 60 of the second prior art, the load is applied. It is defined as a load in which the load current such as an incandescent lamp is in phase with the load voltage (power factor is 1). Therefore, there is a need for a two-wire type load control device in which the types of loads such as a connected fluorescent lamp and an incandescent lamp are not limited. 8 201034517 3335/pil Further, the bidirectional triode or the transistor used as the main switching element of the main opening and closing portion is made of Si, which is generally a vertical type in which current flows in the longitudinal direction of the element. In the case of the bidirectional triode, there is a PN junction (PN junction) on the energization path, so that the loss occurs when the current is exceeded during energization. Further, in the case of a transistor, since it is necessary to connect two elements in the reverse direction, and the low carrier concentration layer which is a waste metal sustain layer has high resistance, loss occurs during energization. Since these losses cause an increase in the amount of heat generated by the main switching element itself, a large heat sink is required, which hinders the increase in capacity and size of the load control device. In general, such a load control device is housed in a metal case (b〇x) or the like provided on a wall surface. However, in the conventional load control device, there is a limit to miniaturization, so the size of a general-purpose box is now used. In other words, the load cannot be used in conjunction with a control device or other sensor or switch. Therefore, in order to make a small box towel, a spare device and other lying devices are required to be further miniaturized. [Patent Document] The present invention has been developed in order to solve the problems of the above-described prior art, and is provided to reduce the amount of heat generated when the load is energized, and thus In addition, there is no need to limit the load factor of the power factor of the fluorescent lamp or the production load. Another object of the present invention is to provide a load control on the one hand that can accurately control the opening and closing time point on the one hand = 201034517 33357pif Another object of the present invention is to provide a configuration that is equivalent to the second power supply unit. Moreover, it is possible to prevent a load control device that flows a small amount of current in the load during non-operation. A load control device according to a first aspect of the present invention is a two-wire load control device that is connected in series between an AC power source and a load, and includes a main opening and closing unit that is connected in series to a power source and a load, including 1 a gate for applying a control voltage to the connection point, and a main switching element having a transverse double-gate transistor (Duai_ Gate transistor) structure having a withstand voltage portion at i, for supplying power to the load control power; and an auxiliary opening and closing portion The auxiliary switching element including the thyristor structure supplies the load control power source when the main opening/closing portion is non-conductive; the control unit controls the opening and closing of the main opening and closing portion and the auxiliary opening and closing portion; and the second power supply unit from the main Both ends of the opening and closing unit are supplied with electric power via the rectifying unit, and a stable voltage is supplied to the control unit. The second power supply unit supplies electric power from the fourth unit of the main opening/closing unit via the entire unit to stop the supply of electric power to the load. And supplying power to the first power supply unit; the drive circuit driving the main open/close unit to the main opening/closing unit or the auxiliary opening and closing unit When the power is supplied to the load, the power supply is supplied to the load, and the voltage detecting unit is input to the third electric core; The control unit performs control such that the force detecting unit turns on when the voltage detecting unit is turned on for the above-mentioned time period, and is turned on in the second predetermined time period in the main second first predetermined closed portion. According to the first aspect of the present invention, the main switching element of the main opening and closing unit is that the efficiency of the loss (low resistance) of the type 2 load control device is excellent. The lower (sub)chip is composed of (4) ultra-thin crystals, and the film (Semic〇ndUctor is now miniaturized and large-capacity structure). Therefore, the load control device can be implemented from the 2f program (4).开关 Switching element of a transistor structure, _-system: upper = opening and closing part non-conducting, supply of load control power supply 2. Both ends of the main opening and closing unit are supplied with final power via a rectifying unit to supply the control unit The second power supply unit: the second power supply unit supplies power to the second power supply unit when the power supply for stopping the power supply is supplied to the second power supply unit, and the third power supply unit' When the main opening/closing unit or the auxiliary opening/closing unit is closed, when the electric power is supplied to the load, the electric power is supplied to the second power supply unit, and the third power supply unit includes a voltage detecting unit that detects the voltage of the input. And the zero-crossing detection of the load button_the zero-crossing detecting unit, the control unit enters a control that is, when the power is supplied to the load, the above-mentioned first coffee and the third predetermined time are repeated for the time The main opening/closing unit is turned on, and the first predetermined time period is started when the voltage detecting unit detects that the voltage from the wheel to the third power source unit has reached a predetermined threshold value, and the third predetermined time is the zero-crossing. The detection unit detects the zero-crossing of the load current and starts counting, and is less than half a cycle of the load current. 11 201034517 33357pif , half of the fast-paced commercial power supply, even if the time is within the first specified time, Then, the control unit also makes the main opening and closing part non-conducting (== ◎ =, the main opening and closing part is confirmed before the load current is zero; = the opening and closing part does not exceed the zero crossing of the load current and is turned on.): load control of the technical solution The device is characterized by: a switching element of the power supply::: auxiliary body =, a load control, a port auxiliary opening and closing, and a switching element including a thyristor structure, a part, a supply of power to the load (four); control ° * The main opening and closing unit and the opening and closing of the auxiliary opening and closing unit.

Further, Fig. 2 shows a longitudinal sectional configuration of a main switching element of a horizontally-mounted double gate transistor structure. In the configuration shown in FIG. 1B, the source electrodes (SA〇Urceelectrode) S of the two transistor elements are connected to each other and grounded (lowest potential portion) 'source electrode S and gate electrode (or called gate) G1, (there is no need for voltage between 32, and the withstand voltage is required between the gate electrode G1 and the drain electrode D1, D2, so two voltage withstand parts (for example, pull-in resistance = pressure distance) are required. Since the transistor element operates based on the gate electrode reference based on the source electrode, it is possible to drive the gate electrodes G1 and G2 of the respective transistor elements by driving the opposite driving numbers. In contrast, as shown in FIG. It is to be noted that the main switching element of the horizontally-mounted double-electrode transistor structure is configured to realize a bidirectional element having one portion that maintains the devil resistance and has little loss. On the other hand, the element having such a configuration must have the crucible electrode D1. The voltage of D2 is controlled by reference to 13 201034517 3S0y/pit, and it is necessary to input different driving signals to each of the two gate electrodes G1 and G2 (hence, it is called a double gate transistor structure). Fig. 3 is a view of the present invention. Base of load control device 1 of the first embodiment Fig. 4 is a timing chart showing signal waveforms of respective portions of the load control device 1. Further, the specific configuration of the drive circuit 10 is not shown here, and the specific configuration of the drive circuit 10 will be as follows. In the embodiment, the load control device 1 of the first embodiment shown in FIG. 3 is connected in series between the AC power supply 2 and the load 3, and is composed of a main control unit 11 that controls the power supply to the load 3. The drive circuit 10 drives the main opening and closing unit 11; the rectifying unit 12; the control unit 13' controls the entire load control device 1; the first power supply unit 14 supplies a stable power supply to the control unit 13, and the second power supply unit 15 When the power supply to the load 3 is stopped, electric power is supplied to the first power supply unit 14 , and when the electric power is supplied to the load 3 , the third power supply unit 16 supplies electric power to the first power supply unit 14 and the auxiliary opening and closing unit I. Further, the third power supply unit 16 further includes a voltage Θ detecting unit 18 that detects a voltage input to the third power supply unit. The main opening/closing unit 1 includes the above-described horizontal Double brake The main switching element 11a' of the polar crystal structure includes an auxiliary switching element of the thyristor structure. That is, it is convenient to supply electric power to the load 3, that is, in a state where the load control device i is turned off, the current is also rectified from the power source 2 through the power supply. The portion 12 flows to the 2nd 15'th. Therefore, a small current flows on the load 3, but the current is made low, so that the load 3 does not malfunction, and the impedance of the second power 14 201034517 /pll source portion 15 When the electric power is supplied to the load 3, the impedance of the third power supply unit 16 is lowered, and the current flows to the circuit side inside the load control device 1, and the snubber capacitor 25 of the first power supply unit 14 is charged. As described above, the third power source unit 16 is provided with a voltage detecting unit (charge monitoring unit) 18 for detecting the voltage input to the third power source unit 16. When the voltage detecting unit 18 detects that the voltage input to the third power supply unit π has reached a predetermined threshold value, the electric detecting unit 18 rotates a predetermined detection signal. When receiving the detection signal from the voltage detecting unit 18, the control unit 13 outputs the m-thrush signal (main-on_drive signal) for turning on the main opening/closing unit 11 to the drive circuit 10, and the portion U is interposed between the first gauges. Internal conduction (becomes closed). In the configuration example of the control unit 13, the first pulse output unit (the main opening/closing unit drive number) configured to be hard-wired is provided as a part of the control unit 13 (integrated Cireuit). It is also possible to obtain La H (4) based on the detection signal from the voltage detecting unit 18. Alternatively, it is not limited to the output of the central processing unit tj of the illustrated unit, and the output is input to the middle control unit (1 Pr〇). Cessing Unit, CPU, etc., main = 20 ' and software (s〇ftwa: Fu_main is the first to make the main opening and closing unit 11 conductive! The specified time is the age of the door. The comparison = the rate of the power supply is half a cycle shorter After the first predetermined time period has elapsed, the control unit 13 supplements the time (for example, several hundred) when the main door opening/closing unit === is started. In microsecond) conduction (in 201034517 33357pif is closed state). This action makes the main opening and closing part 11 non-conducting, and once the load current begins to flow in the auxiliary opening and closing part Π, then it will continue to flow; the auxiliary opening P is only 1 part 17 until The load current becomes zero. The following example is shown in Figure 3, The second pulse output unit 21 that outputs the second pulse signal (auxiliary opening and closing unit drive signal) for the second predetermined time is provided as a part of the control unit 13 so that the main opening/closing unit u is detected to be non-conductive (open state). Thereafter, the drive signal is applied to the auxiliary opening and closing unit 17 only during the second predetermined time. Further, the second pulse signal may be output in a soft manner, or a diode or a capacitor may be used to cause the delay circuit. Referring to FIG. 4, after the charging operation of the snubber capacitor 25 is completed, the autonomous opening and closing unit 11 supplies power to the load 3 for most of the half cycle of the commercial power source, and then energizes. The electric current is reduced, and then the electric power is supplied to the load 3 from the auxiliary opening and closing unit 17. Further, the auxiliary opening and closing unit π includes the auxiliary switching element 17a of the thyristor structure, and therefore becomes non-conductive at the time point (zero-crossing point) at which the current value is zero (opening) State). If the auxiliary opening and closing unit 17 is rendered non-conductive (open state), the current flows again to the third power supply unit Ο 16, so that every half of the commercial power supply is used. The above operation is repeated. These operations are performed on the load current. Therefore, even if the main opening/closing unit 11 is constituted by the main switching element 11a having a transistor structure, the power factor of the load 3 is not limited to 1, and can be realized. A two-wire type load control device suitable for any of a fluorescent lamp and an incandescent lamp. In the first embodiment, the main opening and closing portion 11 is constituted by a main switching element 11a having a horizontal double gate transistor structure. The portion where the withstand voltage of the transistor element is required is limited to 1 '16 201034517 33357pif; in the case of frequency drift or excessive load, the switching from the auxiliary opening and closing portion 17 to the main opening ^^ is switched The load current path _ acts to protect the auxiliary portion 17

coupler)等的光絕緣半導體開關元件1〇1、 102等而構成。分別對光絕緣半導體開關元件1(n、1〇2的 發光部101a、102a輸入來自控制部13的驅動信號。若有 驅動信號輸入,則光絕緣半導體開關元件1(n、1〇2的發光 部101a、102a將其電力轉換為光能並輸出。若來自發光部 101a、102a的光入射至光絕緣半導體開關元件ι〇1、ι〇2 的光接收部101b、102b,則由光接收部i〇ib、l〇2b進行 光電轉換’將光能轉換為電能(即,發電)。光接收部、 17 201034517 33357pif 102b以如下方式連接,即,此處發電的電力分別以交流電 源(商用電源)以及負載所連接的點為基準(參照圖6) 而對主開閉部11的主開關元件lla的閘極部施加正的電 位。 自控制部13輸出驅動信號而使光絕緣半導 件101、1〇2的發光部101a、102a發光,藉此,容易將驅 動信號輸入至基準電位不同的主開閉部u的主開關元件 lla的閘電極,從而可使主開閉部u的主開關元件Ua成 為導通狀態(閉合狀態)。此外,光絕緣半導體開關元件 ❹ 101、102的發光部101a、i〇2a與光接收部1〇lb、1〇2b電 性絕緣,因此只要不自發光部1〇la、1〇2a輸出光,則驅動 信號就不會輸入至主開關元件lla的閘電極。即,主開關 元件lla的閘電極被供給如下的電力’該電力與自控制部 13輸出的驅動信號不同且與控制部13 (或負載控制裝置 1A的第1電源部14)電性絕緣。又,根據來自控制部13 的驅動信號,一方面可維持絕緣,一方面可使與主開關元 件lla的閘電極連接的光絕緣半導體開關元件1〇1、1〇2 ❿ 容易且確實地接通、斷開。 圖7以及圖8表示圖5以及圖6所示的驅動電路10 的變形例。此變形例中,光電耦合器等的光絕緣半導體開 關元件101、102的發光部1〇la、1〇2a _聯地連接^藉此, 可使流動於驅動電路10的電流值為約1/2,從而可減少驅 動電路10中的電力消耗量。 (第2實施例) 18 201034517 3;3:3ί)7ριί 其次,參照圖9以及圖10,對本發明的第2實施形態 的負載控制裝置1Α中所使用的驅動電路1〇的第2實施例 進行說明。圖5是第1實施形態的負載控制裝置ία的電 路圖,圖6是圖5中的驅動電路10的放大圖。 如圖9以及圖10所示,用於驅動主開閉部11的驅動 電路10是由如下部分構成:對應於主開關元件lla的雙閘 極而分別設置的2組與負載控制裝置1A的第1電源部14 連接的二極體101a、101b,一端連接於各電力線而另一端 連接於二極體l〇la、101b的電容器l〇2a、l〇2b,以及連 接在二極體l〇la、101b與電容器i〇2a、l〇2b的連接點與 主開閉部11的主開關元件lla的各閘極端子之間的驅動開 關元件103a、103b。驅動開關元件i〇3a、i〇3b是藉由來 自控制部13的信號而接通/斷開。此外,該驅動開關元件 103a、103b的構成是,開關部與操作部絕緣。驅動開關元 件103a、103b的構成並無特別限定,如下所述,可使用各 種類型(type)。 根據此構成,經由二極體l〇la、l〇lb而將負載控制 裝置1A的第1電源部14連接在一端連接於電力線的電容 器102a、102b的另一端上,藉此,由該電容器i〇2a、i〇2b 而構成以電力線的電位為基準的簡易電源。對該電容器 102a、102b的充電藉由如下方式進行,即,自電力線中的 電源電壓較高的一側,經由負載控制裝置1A的内部電源 而流至電壓低的一側的電力線的電流對連接於電壓較低的 一侧的電容器進行充電。此時,並未對連接於電壓較高的 201034517 33357pif 1 一側的電容器進行充電,因此,於電源頻率的每一個週期 重複對電容器進行充電。於電力線的電位的關係與上述相 反的時間點’對相反側的電容器進行充電。 當使橫置式雙閘極電晶體結構的主開關元件丨丨a由斷 開而成為接通時,必需以電力線所連接的點(參照圖1〇) 為基準來對主開關元件lla的閘極施加電壓。此處,若根 據來自控制部13的信號使與主開閉部u的主開關元件lu 的閘電極連接的驅動開關元件1〇3&或103b導通,則主開 關元件lla的閘極端子上分別施加有以電力線為基準的充 © 電至電容器的電壓,因此,主開關元件lla成為導通狀態 (閉合狀態)。若主開關元件1 la暫時成為導通狀態則主 開關元件lla的端子間電壓會變得非常小,因此,可利用 自負載控制裝置1A的電源經由二極體i〇ia、以及驅 動開關元件103a、103b而施加的電壓來維持導通。 該實施例中,構成為驅動電路1〇與第1電源部14不 絕緣’因此可高效率地供給驅動電力。電容器1〇2a、 只要暫時確疋主開關元件lla由斷開而成為接通時的閘電 ❹ 極的電位即可,故電容器102a、i〇2b的形狀及容量可為小 型。此外,圖9中是自第i電源部14的輸出對驅動電路 10供給電源,但亦可自第1電源部14的輸入等的比較穩 定的電源部供給電力。 圖11以及圖12表示實施例2的驅動電路的具體 的構成例,作為驅動開關元件l〇3a、l〇3b,使用光電耦合 器或調光繼電器(photo relay)等的光絕緣半導體開關元 20 201034517 S53y/pit 件。若輸入來自控制部13的驅動信號,則自光絶緣半導體 開關元件的發光部輸出光信號,若此光信號入射至光接收 部,則光接收部導通,且流動來自第1電源部14的電流(驅 動信號)。發光部與光接收部電性絕緣,因此,只要不自發 光部輸出光,則驅動信號不會輸入至主開關元件Ua的閘 電極。因此,根據來自控制部13的驅動信號,/方面可維 持絕緣,一方面可使與主開關元件lla的蘭電極連接的驅 φ 動開關元件l〇3a、103b容易且確實地接通、斷開。 圖13以及圖14中表示圖11以及圖12所承的驅動電 路10的變形例。該變形例中,使用了光電柄合器或調光繼 電器等的光絕緣半導體開關元件的驅動開關元件l〇3a、 l〇3b的發光部串聯地連接著。藉此,可使驅動電路1〇中 流動的電流值為約1/2,從而可減少驅動電路10中的電力 消耗量。 圖15以及圖16中表示圖11以及圖a所示的驅動電 路10的另一變形例。該變形例中,使用了光電耦合器或調 光繼電器專的光絕緣半導體開關元件的驅動開關元件 103a、103b的發光部串聯地連接著,而且,在驅動開關元 件103a、103b與主開閉部11力主開關元件Ua的問電極 連接的連接點、與成為該閘電極的基準的電力線之間連接 有電容器购、104b。此外,亦可於圖η以及圖12所示 的驅動電路ίο的構成例中追加電容器i〇4a、i〇4b。 如該變形例所示,追加該電容器104a、104b,藉此, 於驅動開關元件1〇3a、腿接通、斷開時,可利用電容器 21 201034517 , 33357pif 104a,1 〇4b來緩和施加於主開關元件11 a的開電極的電壓 的急遽變化,從而可防止主開關元件11a陡然接通、斷開。 結果’可減少因主開閉部11的主開關元件Ua接通、斷開 而產生的雜訊,故可縮小或省略雜訊濾波器。即,與圖44 或圖45所示的先前例的構成相比,可省略作為雜訊滤波器 而發揮作用的線圈或電容器。 關於構成雜訊滤、波1§的線圈’隨者負载控制裝置的額 定電流變大,該線圈亦變得大型,故只要可省略線圈,則 可實現負載控制裝置的小型化。又,關於構成雜訊濾波器 Θ 的電容器’與線圈相比’其對負載控制裝置大小的限制較 少’但因存在此電容器,故而可降低負載控制裝置為斷開 狀態下的負載控制裝置的阻抗,隨之,對負載控制裝置的 閉合狀態而言並不佳。又,即便於負載控制裝置為斷開的 狀態下,亦經由電容器而流動著交流電流,藉此,斷開時 負载可能發生故障等。因此,若可自負載控制裝置中省略 雜訊濾波器用的電容器,則對二線式負載控制裝置而言成 為較好的形態。 ❹ (第3實施例) 其次,參照圖17以及圖18,對本發明的第丨實施形 態的第3實施例的負載控制裝置⑴進行說明。圖17是第 3實施例的負載控制裝置1B的電路圖,圖18是圖17中的 驅動電路10的放大圖。 該第3實施例中,主開閉部11的驅動電路1〇是由高 頻絕緣變壓器(trance)等藉由電磁耦合而傳送電力的變壓 22 201034517 33357pit 器(電磁耦合元件)103、整流電路l〇4a、l〇4b、振盡電 路105等構成。變壓器1〇3的1次側線圈l03a連接於振後 電路105 ’此外,振盪電路105連接於控制部π。若對振 盪電路105輸入來自控制部13的驅動信號,則僅在施加驅 動信號的期間,振盪電路105振盪,從而產生交流電力。 右變壓器103的1次侧線圈l〇3a中流動由振盪電路1〇5 產生的交流電流’則藉由電磁感應而於2次侧線圈i〇3b、 參 l〇3c中產生電動勢(electromotive force)。於變壓器ι〇3 的2次侧,線圈103b、103c中產生的電動勢為交流電,故 在藉由整流電路l〇4a、104b進行整流後,上述電動勢輸入 至主控制部11的主開關元件11a的閘電極。此外,整流電 路104a、104b以如下方式而連接,即,以商用電源以及負 載所連接的點為基準’對主開關元件11a的閘電極施加正 的電位。此外,變壓器103的1次侧線圈103&與2次侧線 圈103b、103c電性絕緣,因此,只要變壓器1〇3的丨次侧 線圈103a中無電流流動,則驅動信號不會輸入至主開關元 件11a的閘電極。即,主開關元件lla的閘電極被供給有 如下電力,該電力與自控制部13所輸出的驅動信號不同且 與控制部13電性絕緣。 如此,該第3實施例中,將自控制部13輸出的驅動 信號作為觸發(trigger),藉由振盪電路1〇5而產生交流電 力,因此,藉由適當設定振盪電路1〇5中的振盪頻率以及 振幅、變壓器103的1次侧線圈1〇33與2次侧線圈1〇3b、 103c的線圈數等等,可產生變壓器1〇3的2次側線圈 23 201034517

Thus, the current detecting unit 22 is not necessarily required, but may be provided. (First Embodiment) Next, a third embodiment of a drive circuit 1A used in the load control device 1A according to the third embodiment of the present invention will be described with reference to Figs. 5 and 6 . Fig. 5 is a circuit diagram of the load control mA of the first embodiment, and Fig. 6 is an enlarged view of the drive circuit 1A of Fig. 5. As shown in FIG. 5 and FIG. 6, the drive circuit 10 for driving the main opening and closing unit u is an optically-insulating semiconductor switch such as two sets of photo couplers provided corresponding to the double gate of the main switching element 11a. The elements are configured as 〇1, 102, and the like. The drive signal from the control unit 13 is input to the light-emitting portions 101a and 102a of the optically-insulating semiconductor switching element 1 (n, 1 〇 2). If a drive signal is input, the light-insulating semiconductor switching element 1 (n, 1 〇 2 light emission) The portions 101a and 102a convert the electric power into light energy and output the light. When the light from the light-emitting portions 101a and 102a is incident on the light-receiving portions 101b and 102b of the light-insulating semiconductor switching elements ι1 and 〇2, the light receiving portion is received by the light receiving portion. I〇ib, l〇2b perform photoelectric conversion 'converts light energy into electric energy (ie, generates electricity). The light receiving part, 17 201034517 33357pif 102b is connected in such a manner that the electric power generated here is respectively an alternating current power source (commercial power source) And a point at which the load is connected is a reference (see Fig. 6), and a positive potential is applied to the gate portion of the main switching element 11a of the main opening and closing portion 11. The control unit 13 outputs a driving signal to electrically insulate the semiconductor element 101, When the light-emitting portions 101a and 102a of the light-emitting portions 101a are light-emitting, it is easy to input a drive signal to the gate electrode of the main switching element 11a of the main opening and closing portion u having different reference potentials, and the main switching element Ua of the main opening and closing portion u can be made. Conduction Further, the light-emitting portions 101a and i2a of the light-insulating semiconductor switching elements ❹101, 102 are electrically insulated from the light-receiving portions 1?1, 1b, 2b, and therefore, as long as they are not self-illuminating portions 1a, When 1 〇 2a outputs light, the drive signal is not input to the gate electrode of the main switching element 11a. That is, the gate electrode of the main switching element 11a is supplied with electric power which is different from the driving signal output from the control unit 13 and It is electrically insulated from the control unit 13 (or the first power supply unit 14 of the load control device 1A). Further, based on the drive signal from the control unit 13, the insulation can be maintained on the one hand, and the gate electrode of the main switching element 11a can be provided on the other hand. The connected light-insulating semiconductor switching elements 1〇1, 1〇2 ❿ are easily and surely turned on and off. Fig. 7 and Fig. 8 show a modification of the driving circuit 10 shown in Figs. 5 and 6. The light-emitting portions 1〇1a and 1〇2a_ of the optically-insulating semiconductor switching elements 101 and 102 of the photocoupler or the like are connected in series, whereby the current value flowing through the driving circuit 10 can be made approximately 1/2. The amount of power consumption in the drive circuit 10 is reduced. (2) The second embodiment of the drive circuit 1A used in the load control device 1 according to the second embodiment of the present invention will be described with reference to FIG. 9 and FIG. Fig. 5 is a circuit diagram of the load control device ία of the first embodiment, and Fig. 6 is an enlarged view of the drive circuit 10 of Fig. 5. As shown in Figs. 9 and 10, the drive circuit 10 for driving the main opening and closing portion 11 is Two sets of diodes 101a and 101b respectively connected to the first power supply unit 14 of the load control device 1A are provided corresponding to the double gates of the main switching element 11a, and one end is connected to each power line and the other end is connected. The capacitors l〇2a, l〇2b of the diodes l〇la, 101b, and the main switch connected to the connection point of the diodes l〇la, 101b and the capacitors i〇2a, l2b and the main opening and closing portion 11 The switching elements 103a, 103b are driven between the respective gate terminals of the element 11a. The drive switching elements i 〇 3a, i 〇 3b are turned on/off by a signal from the control unit 13. Further, the drive switching elements 103a and 103b are configured such that the switch portion is insulated from the operation portion. The configuration of the drive switching elements 103a and 103b is not particularly limited, and various types can be used as described below. According to this configuration, the first power supply unit 14 of the load control device 1A is connected to the other end of the capacitors 102a and 102b whose one end is connected to the power line via the diodes 1a and 1b, whereby the capacitor i is 〇2a and i〇2b constitute a simple power source based on the potential of the power line. The charging of the capacitors 102a and 102b is performed by connecting a current pair of the power line flowing to the lower voltage side via the internal power source of the load control device 1A from the side where the power source voltage in the power line is higher. The capacitor on the lower voltage side is charged. At this time, the capacitor connected to the higher voltage of the 201034517 33357pif 1 side is not charged, so the capacitor is repeatedly charged every cycle of the power supply frequency. The relationship between the potential of the power line and the time point opposite to the above is charged to the capacitor on the opposite side. When the main switching element 丨丨a of the horizontal double gate transistor structure is turned off and turned on, it is necessary to connect the gate of the main switching element 11a with reference to the point at which the power line is connected (see FIG. 1A). Apply voltage. Here, when the drive switching element 1〇3& or 103b connected to the gate electrode of the main switching element lu of the main opening/closing unit u is turned on according to a signal from the control unit 13, the gate terminal of the main switching element 11a is applied separately. Since the voltage is charged to the capacitor based on the power line, the main switching element 11a is turned on (closed state). When the main switching element 1 la is temporarily turned on, the voltage between the terminals of the main switching element 11a becomes extremely small. Therefore, the power supply from the load control device 1A can be used to pass through the diode and drive the switching element 103a. The voltage applied by 103b maintains conduction. In this embodiment, the drive circuit 1A is not insulated from the first power supply unit 14, so that the drive power can be efficiently supplied. The capacitors 1A and 2a are only required to temporarily correct the potential of the gate electrode when the main switching element 11a is turned off, so that the shapes and capacities of the capacitors 102a and i2b can be small. In addition, in Fig. 9, power is supplied to the drive circuit 10 from the output of the i-th power supply unit 14, but electric power may be supplied from a relatively stable power supply unit such as an input of the first power supply unit 14. 11 and FIG. 12 show a specific configuration example of the drive circuit of the second embodiment, and as the drive switching elements 10a and 3b, an optically insulating semiconductor switching element 20 using a photocoupler or a photo relay is used. 201034517 S53y/pit pieces. When a drive signal from the control unit 13 is input, an optical signal is output from the light-emitting portion of the optically-insulating semiconductor switching element, and when the optical signal is incident on the light-receiving portion, the light-receiving portion is turned on, and the current from the first power supply unit 14 flows. (drive signal). Since the light-emitting portion is electrically insulated from the light-receiving portion, the drive signal is not input to the gate electrode of the main switching element Ua as long as the light is not emitted from the light-emitting portion. Therefore, according to the driving signal from the control unit 13, the insulation can be maintained, and on the other hand, the driving switching elements 103a, 103b connected to the blue electrode of the main switching element 11a can be easily and surely turned on and off. . A modification of the drive circuit 10 shown in Figs. 11 and 12 is shown in Figs. 13 and 14 . In this modification, the light-emitting portions of the drive switching elements 10a, 3b, 3b of the optically-insulating semiconductor switching element such as a photoelectric aligner or a dimming relay are connected in series. Thereby, the current value flowing in the drive circuit 1 can be made about 1/2, so that the amount of power consumption in the drive circuit 10 can be reduced. Fig. 15 and Fig. 16 show another modification of the drive circuit 10 shown in Figs. 11 and a. In this modification, the light-emitting portions of the drive switching elements 103a and 103b using the photo-insulating semiconductor switching elements of the photocoupler or the dimming relay are connected in series, and the switching elements 103a and 103b and the main opening and closing unit 11 are driven. A capacitor connection 104b is connected between the connection point of the electrode connection of the main switching element Ua and the power line which serves as a reference for the gate electrode. Further, capacitors i 〇 4a and i 〇 4b may be added to the configuration examples of the drive circuit ί shown in Fig. 11 and Fig. 12 . As shown in this modification, by adding the capacitors 104a and 104b, the capacitors 21 201034517 and 33357pif 104a, 1 〇 4b can be used to relax the application to the main unit when the switching elements 1〇3a and the legs are turned on and off. The voltage of the open electrode of the switching element 11a is rapidly changed, so that the main switching element 11a can be prevented from being suddenly turned on and off. As a result, noise generated by turning on and off the main switching element Ua of the main opening and closing portion 11 can be reduced, so that the noise filter can be reduced or omitted. That is, the coil or the capacitor functioning as a noise filter can be omitted as compared with the configuration of the previous example shown in Fig. 44 or Fig. 45. In the coil constituting the noise filter and the wave 1 §, the rated current of the load control device is increased, and the coil is also large. Therefore, if the coil can be omitted, the load control device can be downsized. Further, the capacitor constituting the noise filter Θ has a smaller limit on the size of the load control device than the coil. However, since the capacitor is present, the load control device can be reduced in the off state. The impedance, in turn, is not good for the closed state of the load control device. Further, even when the load control device is off, an alternating current flows through the capacitor, whereby the load may be broken or the like at the time of disconnection. Therefore, if the capacitor for the noise filter can be omitted from the load control device, it is preferable for the two-wire type load control device. (Embodiment 3) Next, a load control device (1) according to a third embodiment of the third embodiment of the present invention will be described with reference to Figs. 17 and 18 . Fig. 17 is a circuit diagram of the load control device 1B of the third embodiment, and Fig. 18 is an enlarged view of the drive circuit 10 of Fig. 17. In the third embodiment, the drive circuit 1A of the main opening/closing unit 11 is a transformer 22 that transmits electric power by electromagnetic coupling such as a high-frequency insulating transformer or the like. 201034517 33357pit (electromagnetic coupling element) 103, rectifier circuit 1 〇4a, l〇4b, vibration circuit 105, and the like. The primary side coil 107a of the transformer 1〇3 is connected to the post-resonance circuit 105'. Further, the oscillation circuit 105 is connected to the control unit π. When the drive signal from the control unit 13 is input to the oscillation circuit 105, the oscillation circuit 105 oscillates only during the application of the drive signal, thereby generating AC power. The alternating current ' generated by the oscillation circuit 1〇5 in the primary side coil 10〇3a of the right transformer 103 generates an electromotive force in the secondary side coil i〇3b and the reference l〇3c by electromagnetic induction. . On the secondary side of the transformer ι〇3, the electromotive force generated in the coils 103b and 103c is alternating current, and therefore, after the rectification by the rectifying circuits 104a and 104b, the electromotive force is input to the main switching element 11a of the main control unit 11. Gate electrode. Further, the rectifying circuits 104a and 104b are connected such that a positive potential is applied to the gate electrode of the main switching element 11a with reference to a point at which the commercial power source and the load are connected. Further, since the primary side coil 103& of the transformer 103 is electrically insulated from the secondary side coils 103b and 103c, the drive signal is not input to the main switch as long as no current flows in the secondary side coil 103a of the transformer 1〇3. The gate electrode of element 11a. That is, the gate electrode of the main switching element 11a is supplied with electric power which is electrically insulated from the control unit 13 unlike the drive signal output from the control unit 13. As described above, in the third embodiment, the drive signal output from the control unit 13 is used as a trigger, and the AC power is generated by the oscillation circuit 1〇5. Therefore, the oscillation in the oscillation circuit 1〇5 is appropriately set. The frequency and amplitude, the number of coils of the primary side coil 1〇33 of the transformer 103 and the secondary side coils 1〇3b and 103c, etc., can generate the secondary side coil 23 of the transformer 1〇3 201034517 33357pif I: Π Even when the main The main mode of the current type of the main value of the opening and closing portion 11 can also be stably driven. In addition, the crane power of the electric circuit 105 is of course supplied by any part of the load (four) device. Alternatively, although not shown, it is also possible to omit the electric == the self-controlling 13 directly outputs the predetermined _ and the pulse of the predetermined amplitude (fourth embodiment). Fig. 19' shows the fourth embodiment of the first embodiment of the present invention. The actual device 1 will be described. The load control of the above embodiment = the main switching element of the opening and closing portion U is applied with a driving signal: the current is made by the diode of the rectifying portion 12, and the current is equal to the main switching element. In the Ua / two lit embodiment of the voltage type above the current value of the second solid state, even when the main switching element of the main opening and closing portion 11 ❹ p (four) the core I 疋 value or solid When the main switch of the current type having a current value of more than the value is used, it can be stably driven. In the load control device 1B of the fourth embodiment, the AC line of the first embodiment and the negative portion of the rectifying unit serving as the circuit reference are the same as the main opening and closing unit U, and the switching elements 12A and 12B are tested. ,! When the switch is turned on, the synchronous switching element is made synchronously. When the operation of closing the main opening/closing portion 11 is the same as that of the closing of the components 120a and 120b, the main power supply unit 14 that causes the current from the inside to the main opening and closing portion 11 is formed as the main switch 24a. The path through which the gate is flowing. Therefore, even if the gate portion of the main switching element 11a is a double gate element requiring current, it can be stabilized. In addition, the other components or basic actions are related to the situation in the above-mentioned real customs. (Fifth Embodiment) ❹ m , the second 'parameter 20 and the second embodiment will be described with respect to the load control device 1c of the fifth embodiment.

(Embodiment 6) Next, a load control device id according to a sixth embodiment of the first embodiment of the present invention will be described with reference to Figs. 22 to 24 . Fig. 22 is a circuit diagram showing a configuration of the load control device 1D of the sixth embodiment, Fig. 23 is an enlarged view of the drive circuit 10 of Fig. 22, and Fig. 24 is a timing chart showing signal waveforms of respective portions of the load control device 1D. . In the load control device 1D of the sixth embodiment, the drive circuit 10 of the main opening/closing unit 11 is composed of a high-voltage diode 101a, 101b' connected to the first power supply unit 14 of the load control device 1D.

When the charging completion detection is performed by the voltage detecting unit 18 provided in the third power supply unit 16, the operation is shifted to the main opening/closing unit u. At this time, a signal is input in order to turn on the driving switching elements 105a and 105b connected to the gate electrode of the main switching element 11a of the main opening and closing unit 11, but the driving switching elements 105a and 105b are thyristors or bidirectional triodes. Therefore, it is only necessary to drive the switching element 105a and the drive of the position as a trigger signal. Therefore, the driving power of the driving switching elements 10a, 5b, 5b can be reduced as compared with the driving power in the above-described respective embodiments. Further, in order to make the drive switching elements H) 5a and 105b non-conductive, the synchronous switching elements 12Ga and 120b provided in the rectifying unit 12 can be opened, whereby the driving power for opening and closing the cymbal 11 can be reduced.

That is, the 'third pulse' rises from the zero-crossing check $^2nd 2^^ signal, and falls after the third predetermined time. The second pulse output unit 24 detects that the main opening/closing unit is a handsome (open (5) recording specification _ 2nd money, so that the opening and closing unit 17 is turned on only for the second predetermined time. The pulse rises after detecting that the main opening and closing portion 11 is non-conductive (open state), and then falls after the second predetermined time elapses. That is, it is convenient to supply electric power to the load carrier 3, that is, in a state where the load control device 1 is turned off. Since the power source 2 flows to the second power supply unit 15 via the rectifying unit 12, a small current flows in the load 3, but the current is suppressed.

When power is supplied to the load 3, the resistance current of the third power supply unit 16 is lowered to the circuit side inside the load control device 1A, and the snubber capacitor 29 of the flute unit 14 is charged. As described above, the voltage detecting unit (charge monitoring unit) 18 is provided in the 5 16 portion, and the voltage to the 卩 16 is detected. When the voltage detecting unit 18 turns on the voltage of the power source unit 16 has reached the regulation. The threshold value, the control unit 13: U Γ predetermined detection signal is output to the control unit 13. When the detection signal of the closed portion u is detected by the whistle detection unit 18, the main opening is performed; the first regulation time is turned on (becomes closed) In the state of Fig. i, the portion of the control unit 13 is provided, and the first pulse wheeling portion 19 configured to be used in accordance with the electric secret is provided so that the detection signal of the number is directly outputted to the first pulse. The signal voltage detecting unit may be configured such that the main control unit including the free PU or the like turns on the pulse gas signal. The main opening/closing unit η is preferably set to be a commercial frequency power source. 29 201034517 33357pif When the first predetermined period of time has elapsed, when the closing portion 11 is started to be non-conductive (open state), the main opening assisting opening and closing unit 17 is caused only for the second predetermined time (for example, One hundred seconds portion 13 makes (closes In this operation, the conduction portion 11 in the auxiliary opening and closing portion 17 may be turned into a non-conformity (open state) a little later. The main control unit 20 is closed, and the auxiliary switching unit 17 outputs a first pulse signal that is self-exiting. Only the second predetermined time pulse is generated: two or two rounds, or a diode or a capacitor can be used to form the delay circuit. By these actions, after the snubber capacitor 29 is charged, the half of the power supply is used. The main opening and closing portion 丨1 is replaced by the main opening and closing portion 大部分1 after the current supply current is reduced, and the electric power is supplied from the auxiliary opening and closing portion. Further, the auxiliary opening and closing portion 17 includes the intermediate fluid structure=switch 70 member 17a'. When the current value is zero (the zero-crossing point 非^ is non-conducting (open state). If the auxiliary opening and closing unit 17 becomes non-conductive (hit = the current flows again to the third power supply unit 16, the mother half cycle repeats the above) The electric sequence diagram 26 shows the signal of each part of the load control device pressure at the time of high load; Fig. 27 and Fig. 28 show the signal waveform of the load control device 低 at the time of low load. Further, Fig. 27 shows that the mosquito is used only. on Fig. 28 shows a case where the main opening/closing unit 11 is controlled by using the first vouching and the third circumstance. _ When the load 3 connected to the two loads is high capacity, as shown in Fig. 26 τ, the rusher 29 is charged in a short time, after the completion of the charging, 201034517 33357pii supplies power to the load 3 by the main opening and closing unit U for most of the half cycle of the commercial power supply. The i-th predetermined time is set so that the main opening/closing unit u is non-conducting before the time point (zero-crossing point) at which the current value is zero, so that the main opening/closing unit U does not exceed the zero-crossing point to be in an ON state. However, when the load is low, That is, the connected load 3 has a low capacity; the current of the ,, ❿ 较小 is small, so charging takes more time. Therefore, as shown in Fig. 27, the time until the zero-crossing detection unit 23 detects the zero-crossing period until the voltage detecting unit 18 detects the completion of the charging becomes long, and the rise of the second pulse is delayed. The i-th predetermined time is set in accordance with the case of the above-described high load. Therefore, if the rise of the first pulse is excessively delayed, the load current exceeds the _ drop. Therefore, when only the first pulse balance is used, the main opening/closing unit U is turned on beyond the zero-crossing point at a low load, and the charging operation is unstable every half cycle. In the present embodiment, the main opening/closing unit u is restricted to the 2nd state by using the third pulse output unit 21 to rotate = 3 pulses' for the third predetermined time. The third pulse receives the rise of the zero-crossing detection by the zero-crossing detecting unit 23, and falls after the third predetermined time elapses. At the third predetermined time, the weight is shorter than the half cycle of the load current. The ith pulse output from the first pulse output unit 19 and the third pulse output from the third pulse output unit 21 are input to the control unit Π. Control department

Thereby, the main opening/closing unit u is closed only for a time period in which the first predetermined time of the third step is repeated and the third predetermined time of the third pulse rises. As described above, the third pulse rises at the time point when the zero-crossing detecting unit 23 31 201034517 33357pif detects the zero-crossing point, and falls in the third predetermined period which is shorter than the half-cycle of the load current. Therefore, even if the buffer is detected When the charging of the capacitor 29 is completed, that is, the deviation occurs after the time point at the start of the first predetermined time, the main opening/closing unit u does not exceed the zero-crossing point of the power supply frequency to be in the closed state. Thereby, it is indeed possible to charge every half cycle, thereby making the action stable. These actions are performed for the load current. Therefore, even if the main opening and closing portion U is constituted by the transistor structure Ha, the power factor of the load 3 is not limited to i, so that it is suitable for the flashlight and the incandescent lamp. Among the two-wire control devices, and because the main opening and closing portion is a closed element composed of a double-gate type transistor, the load control device can also be realized in a small size and a large capacity. According to the load control agricultural device of the second embodiment, when the portion 18 detects that the voltage of the input to the third electric_16 has reached the predetermined limit value, the control unit 13 causes the main opening/closing unit u to be within the first predetermined time. When it is turned on (closed (five)', the main opening/closing unit 11 supplies electric power to the load during the half-eighth time of the half cycle of the commercial power supply. Further, even if it is the first predetermined time, (3) The main opening/closing portion 11 is also rendered non-conductive (turned on), so that the work is delayed at the time when the first predetermined time starts at the load, and the main opening/closing portion is also Will become a gate = does not exceed the zero crossing of the load current and is turned on, so the battery is reliably charged during the half cycle of the power supply. "", after the e-th specified time, when turned on, only the third gauge (4) The auxiliary opening and closing unit is turned on, and = 32 201034517 After the load is supplied to the load in the half cycle of the commercial power source, the main opening and closing unit supplies power to the load in the energization time period. After that, since the auxiliary opening and closing department, even the main The opening and closing part u is carried out by Xiagu 1疋 for the load current, and the power factor of the load is also the U-crystal structure of the switching element 1U combined with the fluorescent lamp and the incandescent money, so that it can be realized. The second-line load control device (leve.) of the protection system can be used in a wide range of negative load. The third embodiment is implemented. (Fig. 29) The device will be described with reference to Fig. 29. The load control module 1 5' of the second embodiment includes a current detecting unit 22 for detecting a current flowing in the auxiliary opening and closing unit 17, and a self-current detecting unit.

The OR circuit 25b is provided in the subsequent stage of the AND circuit 仏 of the control unit 13. It is desirable that the auxiliary opening and closing unit 17 is for detecting the zero-crossing point of the original current, and does not have the main purpose of energization, and is constituted by a small switch element. However, if the frequency is shifted in the commercial power supply and the load control device can operate at 50 Hz and 60 Hz, the time until the self-opening and closing portion becomes non-conducting until the zero-crossing point of the current increases, and the load current changes. After the charge is small, the power supply to the auxiliary opening and closing unit is started. 33 201034517 33357pif When the load is too large, the following may occur: • Even if the energization time of the auxiliary opening and closing unit is the same, the energization loss increases, and the switching element that constitutes the auxiliary unit 17 is broken. Therefore, in the third embodiment, the current value flowing through the auxiliary opening and closing unit 17 is detected by the flow detecting unit 22, and when the current exceeding the current value permitted by the auxiliary opening and closing unit 17 flows, the main opening/closing unit is again turned on. 11 is turned on only in a short time (fourth predetermined time) (becomes in a closed state), and thereafter, the auxiliary opening and closing portion 17 is turned on again when the main opening and closing portion U is rendered non-conductive (open state). More specifically, when the current detecting unit 22 detects that a current exceeding the current value allowed by the auxiliary assist opening/closing unit 17 flows, a signal indicating this is output to the 〇R circuit 25b of the control unit 13. When the OR circuit 25b receives any one of the output signal from the AND circuit 25a or the output signal from the current detecting unit 22, the main opening/closing unit 11 is turned on only for a short time to protect the auxiliary opening and closing unit 17. By repeating the switching of the main opening and closing portion 11 and the auxiliary opening and closing portion 17 in this manner, the switching element of the auxiliary opening and closing portion 17 is prevented from being damaged, and the correspondence with the type of the commercial power source or the correspondence with respect to the overload is improved. ❹ ^ According to the load control device IF of the third embodiment, when the current detection #22 detects that a current exceeding the allowable value flows in the auxiliary opening and closing unit 17, the main opening/closing portion is temporarily turned on (closed state), and thereafter, Make it a guide, state. Thereby, the switching element of the auxiliary opening and closing unit 17 is prevented from being broken, and the auxiliary switching unit 17 can be configured by a small switching element, so that the load device can be downsized, and the quality of the commercial power source can be improved or improved. Correspondence for overload. 34 201034517 /pit The present invention is not limited to the configuration of the above-described embodiment, and may be at least configured such that the control unit 13 receives the first completion pulse of the snubber capacitor 29 from the voltage detecting unit 18 and outputs the first pulse. The zero-crossing detecting unit 23 receives the detection signal of the zero-crossing point of the load current and outputs the logical product of the third pulse to control the operation of the main opening and closing unit u. Further, the present invention can be variously modified. For example, the third pulse causes the output from the zero-crossing detecting unit 23 to be input to the main control unit 2B composed of cpu or the like, and outputs the first pulse in a soft manner. signal. (Fourth Embodiment) A load-locking device 1G according to a fourth embodiment of the present invention will be described below with reference to Fig. 30. The basic configuration of the load control device 丨G may be configured by any of the above embodiments and modifications. The load control device 1G of the fourth embodiment is used to control a plurality of lighting fixtures in a non-residential house such as an office building or a commercial facility, for example, an art control panel installed at a location away from the lighting device ( There are a plurality of control boards).

After the ith predetermined time has elapsed, the main opening and closing unit 11 is turned off (open state). At the time of the operation, the control unit 13 turns on the auxiliary opening and closing unit 17 only in the second predetermined time (for example, several hundred microseconds) (in a closed state). In this operation, the auxiliary opening and closing unit 17 may be turned off (open state) slightly later than the main opening/closing unit 11. FIG. 33 shows an example in which a second pulse for outputting a predetermined time is provided as a part of the control unit 13. The second pulse output unit 21 of the signal causes the auxiliary opening/closing unit 17 to be turned on only for the second predetermined time after detecting that the main e opening/closing unit 11 is rendered non-conductive (open state). Further, the main control unit 2 输出 outputs the pulse signal having only the second predetermined time longer than the first pulse signal outputted from the main opening/closing unit 11 to the auxiliary opening and closing unit 17. Alternatively, a diode or a capacitor may be used to constitute the delay circuit.

(Second embodiment) Next, a second embodiment of the load control device used in the fifth embodiment of the present invention will be described. Fig. 35 is a circuit diagram showing the configuration of the load control device II of the second embodiment. 33 is different from FIG. 35 in that the load control device u of the second embodiment is different from the load control device 1H of the second embodiment in that it further includes a current for flowing to the auxiliary opening and closing portion 17. The detected current detecting unit 22. The other aspects are the same. 39 201034517 33357pif The description in the previous example shown in the section ’ “The auxiliary material is required to be opened and closed ( 原来 原来 原来 原来 原来 原来 原来 原来 原来 原来 原来 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 However, if the frequency shifts in the commercial-source or the load control device can perform the operation at both % Η and 60 Hz, the time until the autonomous opening and closing portion becomes the zero-crossing point of the current increases, and the load current becomes sufficient. Before starting small, the auxiliary opening and closing unit is energized. Further, when the load is excessively large, the following monthly conditions may occur. Even if the energization time of the auxiliary opening and closing portion is the same, the "energization loss is increased", and the switching element constituting the auxiliary opening and closing portion is broken. Therefore, in the second embodiment, the current detecting unit 22 detects the current value flowing through the auxiliary opening and closing unit 17, and when the current exceeds the current value allowed by the auxiliary opening and closing unit 17, the main opening/closing unit is again turned on. u is turned on only in a short time (becomes in a closed state), and thereafter turns on the auxiliary opening and closing portion 17 again when the main opening/closing portion U is rendered non-conductive (open state). By repeatedly switching the main opening and closing portion 11 and the auxiliary opening and closing portion 17 in this manner, the switching elements of the auxiliary opening and closing portion 17 are prevented from being damaged, and the correspondence with the type of the commercial power source is improved or the correspondence with the overload is improved. Fig. 36 shows waveforms when the load control device II of the second embodiment performs an operation. (Third embodiment) Next, a third embodiment of the load control device used in the fifth embodiment of the present invention will be described. Fig. 37 is a circuit diagram showing the configuration of a load control device 1J of the third embodiment. Compared with FIG. 35, the load control device 1J of the third embodiment is basically the same as the load control devices 1H and II of the first and second embodiments described above, except that it constitutes the main opening 40 201034517 closed portion 11 The switching element lib is constituted by a horizontally-transparent transistor element that can be controlled bidirectionally. In addition, FIG. 37 is a standard of the load control device II of the second embodiment shown in FIG. 35. However, the present invention is not limited thereto, and may be the same as the load control device iH of the first embodiment shown in FIG. Ground composition. Fig. 38 shows a schematic configuration of a laterally mounted transistor element which can be controlled bidirectionally. Such a transverse transistor element is called a High Electron Mobility Transistor (HEMT), and utilizes a two-dimensional electron gas (electr〇n gas) layer generated on a ❹A1GaN/GaN hetero interface. As a channel (channei) layer, an electrode D1 and an electrode D2 and a control electrode (gate) G are formed on the surface of the substrate, and the electrodes D1 and D2 are connected in series to the power source 2 and the load 3, respectively. The electrode (gate) G controls the electrode D1 and the electrode D2 to maintain a high withstand voltage when the electrode D1 and the electrode D2 are turned off. As the control electrode G, for example, a Schottky electrode can be used. When the main opening/closing unit 11 is non-conductive (open state), the self-control unit 13 applies a low level of money to the control electrode G. However, in this control, the potential of the pole G is lower than the lowest potential of the main opening/closing unit u. One diode that is higher than the entire 12. Here, as long as it is sufficiently higher than one of the above-mentioned two-body and potential, the threshold of the conduction (closed state) non-= (open state) of the main opening/closing unit u can be switched to surely maintain the material feed (opening: two In the first aspect, the main opening/closing unit 11 is in an ON state (closed state). The same operation as in the case of the above-described first to third embodiments is performed. The control unit driven by a control signal of several v is used to directly 201034517 33357pif control, high voltage commercial power supply. X, by using a HEMT with high electron mobility, the two-wire load control device can be realized with a small size and high capacity. (Fourth Embodiment) Next, the present invention is The fourth embodiment of the load control device used in the fifth embodiment will be described. Fig. 39 is a circuit diagram showing the configuration of the load control device 1K of the fourth embodiment. The load control device 1K of the fourth embodiment basically has the above-described configuration. The load control devices 1H to 1J of the first to third embodiments are the same, but the difference is that the switch member 11c constituting the main opening and closing portion u is constituted by a novel horizontally-transparent transistor element which can be controlled bidirectionally. 39 is a standard of the load control device 1J of the third embodiment shown in FIG. 37. However, the present invention is not limited thereto, and the load control device 1H or the diagram of the first embodiment shown in the drawings may be used. The load control device II of the second embodiment shown in Fig. 35 is configured in the same manner. Fig. 40 is a plan view showing the configuration of the switching element ile, and Fig. 41 is a cross-sectional view taken along line AA of Fig. 40. As shown in Fig. 41, the switching element llc is shown. The substrate 120 is composed of a conductor layer 120a, a GaN layer ❾ 120b laminated on the conductor layer 12A, and an AlGaN layer 120c. The switching element iic is formed by using a two-dimensional electron gas layer generated on the AlGaN/GaN hetero interface. As shown in FIG. 40, the first electrode D1 and the second electrode D2 which are respectively connected in series to the power source 2 and the load 3, and the first electrode D1 are formed on the surface 12 of the substrate 12A. The potential and the potential of the second electrode D2 are intermediate potential portions S of the intermediate potential. Further, a control electrode (gate) is formed on the intermediate potential portion S. As the control electrode 42 201034517 3335/ρΐί G, for example Use a Schottky electrode. The !! electrode D1 and The two electrodes D2 are comb-like shapes each including a plurality of electrode portions m, U2, 113, ... and 121, 122, 123, ..., which are arranged in parallel with each other, and are arranged in a comb-like arrangement of electrode portions. The intermediate potential portion s and the control electrode G are respectively disposed between the electrode portions ... and 121 122 123 ..... arranged in a comb-tooth shape, and have an electrode formed in the electrode The shape of the space between the parts is similar (substantially fishback bone shape). ❹ , , , , , , , , , , 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 As shown in FIG. 40, the electrode portion iu of the i-th electrode m and the electrode portion 121 of the second electrode D2 are arranged such that the center line in the width direction thereof is located on the same-line "corresponding portion of the intermediate potential portion s and the control electrode G The corresponding portions are disposed in parallel with the arrangement of the electrode portions m2 of the i-th electrode m and the electrode portions 121 of the electrode D2, respectively. In the width direction, the electrode portion U1 of the electrode D1, the electrode portion 121 of the second electrode D2, the corresponding portion of the potential portion S, and the corresponding portion of the control electrode G are set to maintain a predetermined withstand voltage. distance. The direction orthogonal to the width direction is the same as the longitudinal direction of the electrode portion in the first electrode D1 and the electrode portion 121 in the second electric = 2. These relationships are also the same for the other electrode portions 112, 122, m, and 123.. In other words, the intermediate potential portion S and the control electrode G are disposed at positions where the predetermined withstand voltage can be maintained with respect to the first electrode D1 and the second electrode D2. The intermediate potential portion s having an intermediate potential with respect to the potential of the first electrode D1 and the second electrode D2', and the control electrode 43 for controlling the intermediate potential portion 8 connected to the middle B US 201034517 33357pif 2 is disposed at a position where the voltage of the first electrode m and the second electrode 维持 can be maintained. Therefore, for example, when the i-th electrode is at the high potential side and the second electrode D2 is at the low potential side, When the switching element iic is turned off, that is, when the signal of ov is applied to the control electrode G, the current is surely cut off at least between the first electrode D1 and the control electrode G and the intermediate potential portion § (current is applied to the control electrode (gate) ) G is blocked directly below). The other aspect is when the bidirectional switching element Uc is turned on, that is, at the control electrode

Until the limited level, the switching element llc can be surely turned on/off, so that a low on-resistance can be achieved. Further, by using the novel switching element lie, the main opening and closing portion u' makes the potential of the reference (GND) different from the intermediate potential portion s according to the control signal, whereby it can be driven by the control signal of several v. The control unit 13 directly controls the high voltage commercial power source. Further, compared with the case of the third embodiment, the voltage drop due to the diode of the rectifying unit 12 is not affected, and therefore, the conduction (closed state)/non-conduction of the switching main opening/closing unit 11 is lowered. The threshold voltage of the (open state) can also be surely maintained non-conducting (open state). In addition, 44 201034517 33357pii In the transverse-type transistor element using the two-dimensional electron gas layer generated on the hetero interface as the channel layer, the potential of the non-conduction threshold voltage is increased and the on-resistance is turned on. In the opposite relationship, if the threshold voltage can be lowered, the lower on-resistance can be maintained, and the load control device can achieve a small size and a high capacity. (Sixth embodiment) Next, a description will be given of a load control device according to a sixth embodiment of the present invention. The figure is a circuit diagram showing the configuration of the load control device 1L of the sixth embodiment. The load control device 1L of the sixth embodiment is basically the same as the load control devices 1H to 1K of the fifth embodiment, but the third power supply unit 16 includes the zero-crossing detecting unit 23, and the control unit 13 The third pulse output unit 24 is included. In addition, FIG. 42 is a standard of the load control device II of the second embodiment shown in FIG. 35. However, the present invention is not limited thereto, and the load control device 1 of the first embodiment shown in FIG. 33 may be used. The load control device 1J of the third embodiment shown in Fig. 37 or the load control device 1 of the fourth embodiment shown in Fig. 39 is configured in the same manner. The zero-crossing detecting unit 23 detects the zero-crossing point of the load current, and outputs a zero-crossing detection signal indicating the meaning to the third pulse output unit 24. Third, when the zero-crossing detecting unit 23 receives the round-in of the zero-crossing detecting signal from the zero-crossing detecting unit 23, the third pulse is output. The third pulse rises from the zero-crossing detection unit 23 after receiving the zero-crossing detection signal, and falls after the third predetermined time elapses. The third predetermined time is set to be less than half a cycle of the load current. The first pulse output from the first pulse output unit 19 and the third pulse rotated from the third pulse output unit 24 are input to the control unit 13. Control ^ 45 201034517 33357pif Π Includes AND circuit 25a ’ Get the first! The logical product of the pulse and the third pulse is rotated by the OR circuit 25b to the main opening/closing portion ii〇〇r circuit 25b, which is provided in the subsequent stage of the AND circuit 控制 of the control unit 13. (10) When the circuit 25b receives any of the output signals from the AND circuit or the output signal from the current detecting unit 2, the main opening/closing unit 11 is turned on only for a short time to protect the auxiliary opening and closing unit 17 . As described above, the main opening/closing unit η is closed only for the time period in which the i-th predetermined period in which the i-th pulse rises and the third predetermined time in which the third pulse rises overlaps. The third pulse is increased by ≥ liter at the time point when the zero-crossing detecting unit 23 detects the zero-crossing point, and falls in the third predetermined period that is shorter than the half-cycle of the load current. Therefore, even if the charging of the snubber capacitor 29 is detected is completed. At the time point, that is, after the time point from the start of the first predetermined time, a deviation occurs, and the main opening/closing unit 11 does not exceed the zero-crossing point of the power supply frequency to be in a closed state. Thereby, charging can be performed every half cycle, so that the action is stabilized. While the present invention has been described above by way of example, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
