ABSTRACT:
The present invention provides a full-resonant power circuit device for receiving a variable input voltage that a power factor correcting circuit for separating a variable input voltage AC into a plurality of supply voltages, and the input voltage sections are detected to separately switch corresponding switch transistors for suitably adding resonance inductors to the input voltage sections to be used by the full-resonant power circuit device to reduce the large voltage difference of a conventional power factor corrector so as to improve the efficiency of the power circuit device and improve a half-bridge resonance circuit that is only operated in a fixed voltage source.
