Please refer to fig. 2, which is a schematic flowchart illustrating a power supply control method according to an embodiment of the present application. As shown in fig. 2, the power supply control method may include steps S210 to S220, which are detailed as follows:
s210: in the first power supply control mode, power supply control is performed on the power supply device on the basis of a plurality of continuous cycles, the power supply circuit of the power supply device is turned on in the turn-on period of each cycle, and the power supply circuit of the power supply device is turned off in the turn-off period of each cycle.
The power supply circuit of the power supply device refers to a circuit used for supplying power to a load in the power supply device. Taking the power supply apparatus shown in fig. 1 as an example, the power supply circuit of the power supply apparatus may be a power supply circuit composed of a direct current power supply 102, a DC-DC conversion circuit 103, and an AC-DC conversion circuit 104. In other embodiments, the power supply circuit of the power supply device may have other structures, and the structure of the power supply circuit is not particularly limited herein.
The first power supply control mode refers to a mode in which a power supply circuit of the power supply device is controlled to operate intermittently. Based on this, the power supply control strategy corresponding to the first power supply control mode may specifically be: the power supply control method comprises the steps of carrying out power supply control on power supply equipment on the basis of a plurality of continuous cycles, specifically, starting a power supply circuit of the power supply equipment in the starting period of each cycle, and closing the power supply circuit in the closing period of each cycle.
In practical applications, electrical devices such as refrigerators or air conditioners generally have a silent operation mode, in the silent operation mode, main function modules of the electrical devices are turned off, and only a controller and some sensors are in an operation state, for example, a refrigerator enters the silent operation mode after reaching a specific temperature, and in the silent operation mode, a refrigeration module of the refrigerator is turned off, and only the controller and a thermometer are kept in operation. Therefore, when the load of the power supply device is such a power-consuming device with a silent operation mode, the power supply control device may not be able to determine whether the power supply device is loaded, for example, if the refrigerator enters the silent operation mode just during the on period of each cycle and returns to the normal operation mode during the off period of each cycle, the power supply control device may not recognize that the refrigerator is connected to the power supply device, that is, the power supply device is considered to be unloaded, thereby causing an idle load misjudgment.
Therefore, in order to accurately identify the load with the silent working mode, the present application improves the duration of the on period and/or the duration of the off period in a plurality of consecutive cycles, specifically, the sum of the duration of the on period and the duration of the off period in each cycle is equal to the duration of the cycle in each cycle, and the duration of the cycle in each cycle is the same, and for any two adjacent cycles in the plurality of consecutive cycles, the duration of the on period in the next cycle differs from the duration of the on period in the previous cycle by a preset step size, that is, the preset step size is used to describe the duration difference between the on period in the next cycle and the on period in the previous cycle in any two adjacent cycles.
It should be noted that the duration of each period, the preset step length, and the duration of the start-up period in each period may be set according to actual requirements.
For example, for a load with low time accuracy requirement, the duration of the period may be 1 second, the preset step may be 0.1 second, and the duration of the on period in the first period may be 0.1 second. Based on this, the duration of the off period in the first cycle is 0.9 seconds; the duration of the on period in the second cycle is 0.2 seconds, and the duration of the off period in the second cycle is 0.8 seconds; the duration of the on period in the third cycle is 0.3 seconds, the duration of the off period in the third cycle is 0.7 seconds, and so on.
For a load with a high requirement on time accuracy, the period may be 0.1 second, the preset step may be 0.01 second, and the duration of the on period in the first period may be 0.01 second. Based on this, the duration of the off period in the first cycle is 0.09 seconds; the duration of the opening time period in the second period is 0.02 second, and the duration of the closing time period in the second period is 0.08 second; the duration of the on period in the third cycle is 0.03 seconds, the duration of the off period in the third cycle is 0.07 seconds, and so on.
In the embodiment of the present application, the timing when the power supply control device enters the first power supply control mode may include, but is not limited to: (1) starting up the power supply equipment, and when no load is accessed; (2) the power supply equipment is started, a load is connected, the energy-saving mode of the power supply equipment is in an opening state, and the load current is not detected.
S220: and in the starting period of any cycle, under the condition that the load current is detected, the first power supply control mode is exited, the second power supply control mode is entered, and the power supply circuit is controlled to be kept started.
In the embodiment of the present application, the power supply control device may detect the load current in the on period of each cycle while performing power supply control on the power supply device based on a plurality of consecutive cycles, that is, determine whether the load current is detected. In an embodiment of the application, if the power supply control device detects a load current in an on period of a certain cycle, it indicates that a load is connected to the power supply device in the on period of the cycle, and an actual required power of the load is not 0, that is, it indicates that the power supply device is in a non-idle state, at this time, the power supply control device exits from the first power supply control mode, that is, the power supply control device does not perform the step of performing power supply control on the power supply device based on a plurality of consecutive cycles any more, and at the same time, the power supply control device enters into the second power supply control mode.
The second power supply control mode is a mode for controlling the power supply circuit of the power supply device to work continuously, and the power supply circuit is controlled to be kept on in the second power supply control mode. Therefore, after the power supply control device is switched from the first power supply control mode to the second power supply control mode, the power supply circuit is controlled to be kept on.
In the above scheme, since in the first power supply control mode, the power supply device is controlled to supply power based on a plurality of consecutive cycles, the power supply circuit of the power supply device is turned on in the on period of each cycle, the power supply circuit is turned off in the off period of each cycle, and the duration of the on period in the next cycle differs from the duration of the on period in the previous cycle by the preset step length, that is, the duration of the on period in different cycles is changed step by step based on the preset step length, for example, if the trigger time of the silent working mode of the load is 0.1 second as precision, the preset step length may be set to 0.1 second, and if the trigger time of the silent working mode of the load is 0.01 second as precision, the preset step length may be set to 0.01 second, so that the power supply device can identify the load having the silent working mode in the on periods of different cycles, under the condition that the loads are connected, the condition that no-load misjudgment occurs to the power supply equipment can be reduced, the power supply equipment is prevented from supplying power to the misjudged loads, the power consumption requirements of various loads are met, and the application range of the power supply equipment is expanded. In addition, the power supply circuit is only started in the starting time of each cycle, and is closed in the closing time of each cycle, so that the electric energy loss of the power supply equipment can be reduced, and the effective utilization rate of the power supply equipment is improved.
In another embodiment of the present application, the power supply control method may further include the steps of:
and in the starting time periods of a plurality of continuous cycles, if no load current is detected, controlling the power supply equipment to shut down.
In this embodiment, when the power supply control device controls power supply to the power supply device based on multiple continuous cycles, if no load current is detected in the turn-on periods of the multiple continuous cycles, it indicates that no load is connected to the power supply device in the multiple continuous cycles, or indicates that a load is connected to the power supply device in the multiple continuous cycles, but the actual required power of the load connected to the power supply device is low, that is, the power supply device is in an idle state, and at this time, the power supply control device controls the power supply device to turn off.
According to the scheme, when the power supply control device does not detect the load current in a plurality of continuous periods, the power supply device is in the no-load state, and at the moment, the power supply control device controls the power supply device to be shut down, so that the power supply device can be prevented from being in the working state in the no-load state, and the no-load loss of the power supply device is reduced.
Referring to fig. 3, in another embodiment of the present application, the power supply control method may further include S320 to S330, which are detailed as follows:
s320: in the first power supply control mode, the step of performing power supply control of the power supply device on the basis of a plurality of consecutive cycles is executed cyclically, and the number of cycles is recorded.
In this embodiment, the number of the plurality of consecutive cycles is limited, and the number of the plurality of consecutive cycles may be set according to actual requirements, and may be 9, for example.
Therefore, in the first power supply control mode, after the power supply control device performs the power supply control on the power supply device for one time based on the plurality of continuous periods, the power supply control device may continue performing the power supply control on the power supply device for the next time based on the plurality of continuous periods, that is, in the first power supply control mode, the power supply control device may cyclically execute the step of performing the power supply control on the power supply device for the plurality of continuous periods.
When the power supply control device cyclically executes the step of controlling the power supply to the power supply device on the basis of a plurality of consecutive cycles, the number of cycles of the step may be recorded.
In a possible implementation manner, when the power supply control device executes the step of controlling the power supply to the power supply device on a cyclic basis in a plurality of consecutive cycles, it may further detect whether the power supply device is connected once after each execution of the step. Under the condition that no electric equipment is connected, adding 1 to the continuous cycle execution times of the step, and continuing to execute the step for the next time; in the case of the power-using device being connected, it is further determined whether a load current is detected, and in the case of no load current being detected, the number of consecutive loop executions of the step is increased by 1, and the step is continued to be executed next time.
S330: and in the starting time periods of a plurality of continuous periods, if the load current is not detected and the cycle number reaches a preset number threshold, controlling the power supply equipment to shut down.
In this embodiment, if no load current is detected in the turn-on periods of a plurality of consecutive cycles, the power supply control device further determines whether the cycle number of the above steps reaches a preset number threshold. And controlling the power supply equipment to be powered off under the condition that the frequency of the steps reaches a preset frequency threshold value.
The preset number threshold may be determined according to a preset duration of the first power supply control mode, a number of the plurality of cycles, and a duration of each cycle. By limiting the duration of the first power supply control mode, the power supply device can be prevented from being in the first power supply control mode all the time in an idle state, so that the power consumption of the electric device is increased.
For example, if the preset duration of the first power control mode is 15 minutes, the number of the multiple cycles is 9, and the duration of each cycle is 1 second, then 9 seconds are required for performing the step of performing power control on the power supply device based on the multiple consecutive cycles once, and the 15 minutes can be performed in a loop 100 times, so that the preset number threshold may be 100.
In other embodiments, if the power supply control device detects the load current in the on period of any cycle, the power supply control device may enter the second power supply control mode, and perform power supply control on the power supply device based on an actual ratio between the actual required power of the load and the rated output power of the power supply device. It should be noted that, for the specific process of the power supply control device controlling the power supply of the power supply device based on the actual ratio, reference may be made to relevant descriptions in subsequent embodiments, which is not described herein again.
In this embodiment, after the power supply control device enters the second power supply control mode, the number of cycles of the above steps may be reset to 0.
According to the scheme, the power supply equipment is controlled to be shut down by setting the preset frequency threshold value and when the cycle frequency of the step of controlling the power supply of the power supply equipment based on a plurality of continuous periods reaches the preset frequency threshold value, so that the situation that the power supply circuit is continuously and discontinuously started when the power supply equipment is in an idle load state can be avoided, the electric energy loss of the power supply equipment in the idle load state is further reduced, and the effective utilization rate of the power supply equipment is improved.
Referring to fig. 4, in another embodiment of the present application, before S210 in the embodiment corresponding to fig. 2 or before S320 in the embodiment corresponding to fig. 3, the power supply control method may further include S410 to S430, which are detailed as follows:
s410: and detecting whether a load is accessed.
The power supply control device can detect whether a load is connected to the power supply equipment or not after the power supply equipment is started.
In a possible implementation manner, in order to detect the load in time when the load is connected, the power supply control device may detect whether the load is connected to the power supply device in real time after the power supply device is turned on.
In another possible implementation manner, in order to reduce the power consumption of the power supply device, the power supply control device may detect whether a load is connected to the power supply device every preset time interval after the power supply device is turned on. The preset time interval may be set according to actual requirements, and is not particularly limited herein.
In another possible implementation manner, in order to achieve effective detection of the load and reduce the false rate of load detection, an elastic component for detecting whether the load is connected may be disposed on the power supply device, and the power supply control device may determine whether the load is connected by a trigger state of the elastic component.
The elastic component may include, but is not limited to, a spring, a pogo pin, or the like. The activation state of the resilient member may include activated and not activated.
Based on this, S410 may include the steps of:
detecting a trigger state of the elastic component;
if the elastic component is triggered, determining that a load is accessed;
and if the elastic component is not triggered, determining that no load is connected.
In one embodiment, the power supply control means may determine that the elastic member is triggered when it is detected that the elastic member is pressed; when the elastic component is detected not to be squeezed, the elastic component is determined not to be triggered.
In another embodiment, the power supply device may further be provided with a contact corresponding to the elastic member. Based on this, the power supply control device may determine that the elastic member is triggered when detecting that the elastic member is in contact with the contact; when the elastic component is detected not to be in contact with the contact point, the elastic component is determined not to be triggered.
It should be noted that, after the power supply device is turned on, the power supply control device may first enter the second power supply control mode, and in the second power supply control mode, the power supply control device controls the power supply circuit to be turned on, and controls the power supply circuit to maintain the bus voltage at the rated voltage value, that is, controls the power supply circuit to be in a complete working state. The bus voltage of the power supply circuit may refer to a voltage output by a DC-DC conversion circuit in the power supply circuit. The rated voltage value refers to a voltage value corresponding to the rated output power of the power supply device.
S420: if no load access is detected, a first power control mode is entered.
In one possible implementation, the power supply control device may directly enter the first power supply control mode when detecting that no load is connected to the power supply apparatus.
In another possible implementation manner, when the power supply device detects no-load access, it may continuously detect whether a load is accessed, and if it detects load access within a third preset time period, the power supply control device enters the first power supply mode; and if no load is accessed within the third preset time, controlling the power supply equipment to shut down by the power supply control device. The third preset time period may be set according to actual requirements, and is not particularly limited herein.
S430: and if the load access is detected, the energy-saving mode of the power supply equipment is in the starting state, and the load current is not detected within a second preset time after the load access, entering a first power supply control mode.
In this embodiment, the power supply device is preconfigured with an energy saving mode that can be selected by a user. Based on this, under the condition that the load is connected to the power supply equipment, the user can select whether to start the energy-saving mode according to actual requirements. For example, when the load connected to the power supply device is a load without a silent operation mode, the user may select to turn on the power saving mode to reduce the power consumption of the power supply device.
Alternatively, the user may select to turn on or off the power saving mode by operating a mode selection control in a terminal device (e.g., a mobile phone) connected to the power supply device. The mode selection control is a key in a software form, and the mode selection control can be arranged in an application program installed in the terminal equipment.
Alternatively, the user may select to turn on or off the power saving mode by operating a mode selection button provided on the power supply apparatus. Wherein the mode selection button is a physical form of a key.
Based on this, the power supply control device may detect whether the power saving mode of the power supply apparatus is in an on state and determine whether the load current is detected, when detecting the load access.
In one possible implementation manner, when a load is connected and the energy saving mode of the power supply device is in an on state, if the load current is not detected, whether the load current is detected is continuously determined. If no load current is detected within a second preset time after the load is connected to the power supply equipment, the power supply equipment is in an idle state, and at the moment, the power supply control device enters a first power supply control mode.
The second preset time period may be set according to actual requirements, and is not particularly limited herein. For example, the second preset time period may be 300 seconds.
In another possible implementation manner, when a load is connected and the energy saving mode of the power supply device is in an on state, if a load current is detected, it indicates that the power supply device is in a non-idle state, and at this time, the power supply control device may perform S440 to S470 in the subsequent embodiments.
In yet another possible implementation manner, in the case where the load access is detected and the power saving mode of the power supply apparatus is in the off state, the power supply control device may perform S480 in the subsequent embodiment.
According to the scheme, whether the load is accessed is determined based on the trigger state of the elastic component arranged on the power supply equipment, so that the accuracy of load access detection can be improved; the power supply control device enters the first power supply control mode to control the intermittent opening of the power supply circuit, so that the electric energy loss of the power supply device in the no-load state can be reduced, and the electric quantity storage and the effective utilization rate of the power supply device are improved.
Referring to fig. 4, in another embodiment of the present application, after S410, the power supply control method may further include S440 to S470, which are detailed as follows:
s440: and if the load access is detected, the energy-saving mode of the power supply equipment is in an opening state, and the current value of the load current is obtained when the load current is detected.
In this embodiment, the current value of the load current means the value of the current flowing through the load.
In a possible implementation manner, a current collecting circuit for collecting a current value of the load current may be further provided in the power supply device. By way of example and not limitation, the circuit acquisition circuit may include a resistor connected in series in the load loop.
Based on this, when a load is connected, the energy-saving mode of the power supply device is in the on state, and the load current is detected, the power supply control device can obtain the current value of the load current collected by the power supply control device from the current collecting circuit.
S450: and determining the actual required power of the load according to the current value of the load.
In this embodiment, after the power supply control device obtains the current value of the load current, the power supply control device may calculate the actual required power of the load according to the current value. The method for calculating the actual required power of the load according to the current value of the load may be an existing method, and is not described herein again.
S460: an actual ratio between the actual demanded power of the load and the rated output power is calculated.
In this embodiment, the power supply control device may determine a ratio of an actual required power of the load to a rated output power of the power supply apparatus as the actual ratio.
For example, if the actual required power of the load is 9.3 watts and the rated output power of the power supply device is 200 watts, the power supply control device determines that 9.3/200 is 4.65% as the actual ratio. If the actual required power of the load is 30 watts and the rated output power of the power supply device is 200 watts, the power supply control device determines 30/200-15% as the actual ratio.
S470: and starting the power supply circuit, and controlling the bus voltage of the power supply circuit according to the relation between the actual ratio and the preset ratio.
In one possible implementation, the power supply control device may turn on the power supply circuit when the load current is detected. In this implementation, the power supply control device may obtain a current value of the load current while turning on the power supply circuit, and determine the actual ratio; alternatively, the power supply control device may obtain the current value of the load current after the power supply circuit is turned on, and determine the above-described actual ratio.
In another possible implementation manner, when the power supply control device detects the load current, the power supply control device may first obtain a current value of the load current, and after determining the actual ratio based on the current value of the load current, turn on the power supply circuit. The present embodiment does not particularly limit the turn-on timing of the power supply circuit.
In this embodiment, after the power supply control device obtains the actual ratio, the actual ratio may be compared with the preset ratio to determine a magnitude relationship between the actual ratio and the preset ratio, and the bus voltage of the power supply circuit is controlled based on the magnitude relationship.
The preset ratio is used for distinguishing whether the power supply equipment is in an ultra-light load state or a normal load state. In a specific application, the preset ratio may be different according to different application scenarios of the power supply device. For example, the preset ratio may be 5%. Based on this, if the actual ratio is 4.65%, since 4.65% is less than 5%, the power supply control device can control the power supply circuit to lower its bus voltage; if the actual ratio is 15%, since 15% is greater than 5%, the power supply control device may enter a second power supply control mode in which the power supply circuit is controlled to remain on and the power supply circuit is controlled to maintain the bus voltage at the rated voltage value.
Specifically, when the actual ratio is smaller than the preset ratio, it is indicated that the actually required power of the load is low, that is, it is indicated that the power supply device is in an overload state; when the actual ratio is greater than or equal to the preset ratio, the actual required power of the load is normal, that is, the power supply equipment is in a normal load state.
Based on this, in a possible implementation manner, the step of controlling the bus voltage of the power supply circuit according to the magnitude relationship between the actual ratio and the preset ratio may specifically include:
if the actual ratio is smaller than the preset ratio, controlling the power supply circuit to reduce the bus voltage to a first preset voltage value;
and if the actual ratio is greater than or equal to the preset ratio, entering a second power supply control mode and controlling the power supply circuit to be kept on.
And the first preset voltage value is smaller than the rated voltage value corresponding to the rated output power. That is, when the actual ratio is smaller than the preset ratio, the power supply control device may control the power supply circuit to reduce the voltage value output by the DC-DC conversion circuit to the first preset voltage value.
In this embodiment, after the power supply circuit is controlled to reduce the voltage value output by the DC-DC conversion circuit to the first preset voltage value, the present application may continuously cycle to S410 to detect the connection condition of the load.
In all embodiments of the present application, after the power supply control device enters the second power supply control mode, the power supply circuit is controlled to keep on while the bus voltage is controlled to maintain the above rated voltage value by the power supply circuit, that is, the power supply circuit is controlled to be in a full working state.
In this embodiment, the power supply control device may continuously and circularly enter S410 in the second power supply control mode to detect the access condition of the load.
According to the scheme, when the power supply equipment is in the overload state, the voltage value of the bus voltage is reduced, so that the electric energy loss of part of the power supply equipment in the overload state can be reduced, and the effective utilization rate of the power supply equipment is improved.
Referring to fig. 4, in another embodiment of the present application, after S410, the power supply control method may further include S480, which is detailed as follows:
s480: and if the load access is detected and the energy-saving mode of the power supply equipment is in a closed state, entering a second power supply control mode and controlling the power supply circuit to be kept on.
In this embodiment, when a load is connected and the energy saving mode of the power supply device is in the off state, the power supply control device enters the second power supply control mode.
According to the scheme, when the load is connected, but the energy-saving mode of the power supply equipment is in the off state, the second power supply control mode is entered, the power supply circuit is controlled to be kept on, the power supply circuit is enabled to be in the complete working state, and therefore the power supply circuit can supply power to the load normally.
