Background technology
Present stabilized voltage power supply, most with the large product of low pressure and low power.Buck series voltage stabilizing power supply, it usually forms by grid ac voltage and adjusts galvanic current pressure of element output through transformer pressure-reducing, rectification, filtering, series connection, because of the transformer core that uses, has i.e. heavy and heat dissipation problem.The switch-type stabilized power supply is to become high voltage direct current after the direct rectification of grid ac voltage, filtering, and high voltage direct current is reduced to low-voltage alternating-current after high frequency transformer and power switch transistor conversion, then exports one or more DC power supply through lower pressure rectifier filtering; Exist high-voltage load overload or short circuit all can make the deficiencies such as power supply and product burn out.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, proposes a kind of high-frequency and high-voltage magnetic reactance stabilized voltage power supply.
High-frequency and high-voltage magnetic reactance stabilized voltage power supply of the present utility model, it is characterized in that: consisted of by input circuit, varying circuit, output control circuit, 220V is through rectification, filtered mid-point voltage, the output two ends be all the direct current of 190V to power supply ground, then by STC12C5201AD single-chip microcomputer output high-frequency signal, power switch transistor are controlled use and export the high-frequency alternating current that two ends form 200V.
The present invention's beneficial effect compared with prior art: high-frequency and high-voltage magnetic reactance stabilized voltage power supply of the present invention, it is with high voltagehigh frequency output transmission, and output two ends are the equal level of 190V, the fire incident that can effectively avoid electric arc to strike sparks to power supply ground.

Embodiment
As shown in Figure 1: high-frequency and high-voltage magnetic reactance stabilized voltage power supply of the present utility model comprises that input circuit, varying circuit, output control circuit form; 220V is through rectification, filtered mid-point voltage, and output two ends be all the direct current of 190V to power supply ground, then by STC12C5201AD single-chip microcomputer output high-frequency signal, power switch transistor are controlled use and export the high-frequency alternating current that two ends form 200V; Control and switching technique changes the civil power of 220V voltage 50/60HZ frequency into more than high pressure 200V 20KHZ high frequency stabilized voltage power supply by single-chip microcomputer 12C5201AD.
As shown in Figure 1: high-frequency and high-voltage magnetic reactance stabilized voltage power supply of the present utility model, its electric network source be through electric capacity 1 and 3, and choking-winding 2 consists of line filters, prevents circuit or parts that subordinate connects, and the equipment that connects with output produces misoperation; Can decay to conducted noise or the radiated noise of switch power generation, be unlikely to other electronic equipment is produced electromagnetic interference.By bridge rectifier 4, alternating current is transformed into direct current, after filter capacitor 6 filtering, get the high direct voltage of 300V left and right, by magnetic induction loop 5 and diode 7, boost to 9 chargings of electric capacity 8 and electric capacity, filtering gets the high voltage direct current that voltage is about 380V, because electric capacity 8 and electric capacity 9 is series connection, obtain mid-point voltage 190VOUT1.High pressure 380V through field effect transistor 10 and 11 and high frequency transformer 15 consist of translation circuits, thereby the mid-point voltage of getting field effect transistor 10 and 11 is 190V, then is OUT2 by magnetic induction loop 12 outputs.Its single-chip microcomputer 14 is exported respectively high-frequency signal and is controlled field effect transistor 13 and varying circuit.Output two ends are produced frequently become 200V left and right high-frequency alternating current, therefore can be used as voltage and electric current that stabilized voltage power supply coordinates high frequency transformer output various requirement.It is simple in structure, and during use, security performance is high, also can not form the loop even human body directly contacts, and electric shock accidents can not occur, even if the output short circuit can not make power supply damage yet, more can not cause fire.It is the safest product power supply of a existing market.Common power supply is that the civil power of high pressure 220V is exported the low-voltage regulated power supply of high or low power through control circuit, this power supply is to control and switching technique changes the civil power of 220V voltage 50/60HZ frequency into more than high pressure 200V 20KHZ high frequency stabilized voltage power supply by single-chip microcomputer 12C5201AD, and circuit design is the auxiliary products that equalizing voltage has gamut AC input.The traditional frame mode of type voltage regulation power supply is different, and output two ends are all the direct current of 190V to power supply ground, and namely 220V is through rectification, filtered mid-point voltage.By STC12C5201AD single-chip microcomputer output high-frequency signal, power switch transistor is controlled to use again and export the high-frequency alternating current that two ends form 200V; The large electric current that causes when having solved load because of short circuit damages power supply apparatus and product electronic component, high voltagehigh frequency output, make transmission range farther, the fire incident that output can not draw electric arc or be caused by sparking because of high pressure, secondly at output two ends, power supply ground is the equal level of 190V, utilizes singlechip technology output change frequently.
