摘要

Complex resonant type switching converter circuit, which has current resonant circuit and partial voltage resonant circuit in its own primary side, enables extremely high efficiency in power conversion. We have developed this complex resonant converter circuit to reduce harmonic distortion, power factor improvement power supply by voltage feedback form. By using the fast recovery diode and inductance with the voltage resonant type converter power supply's primary resonant voltage from third winding, which feedbacks to the AC rectify capacitor. This circuit are all one-converter from and improves the power factor up to 0.8 by having high efficiency, low cost, small sized, and light.
