PURPOSE: A direct current-alternative current conversion resonance circuit is provided to maximize the energy utilization efficiency by using the low loss AC conversion circuit to reducing current extinction and switching loss. CONSTITUTION: A C1 high-capacity set capacitor(26) and a C2 high-capacity set capacitor(27) is connected serially. A charge and a recharge power supply approval circuit are composed of a C-LC resonance circuit DC power supply(1) and a DC power supply approval switching element(21), a current limiting inductor(22), and a reverse-current prevention diode(23). A voltage sense(103) is connected to both ends of the C1 high-capacity set capacitor. A voltage sense(105) is connected to both ends of the primary winding(4-1) of a transformer(4). A current sense(104) is connected to a load(20) of the secondary winding(4-2) of the transformer. A detection unit(101) changes the digital value from the analog value. A controller(100) transmits a power supply approval driving part(102) the determined command by comparing the digital signal transmitted in the detection unit and the standard value. |
