一种适用于三相隔离全桥Boost PFC变换器的集成变压器无源反激辅助电路

A passive flyback auxiliary circuit with integrated transformer is proposed and investigated in a three-phase isolated full-bridge boost power factor correction (PFC) converter, by which the voltage across primary side of the power transformer can be clamped to a fixed value and the absorbed energy can be transferred to the load by itself automatically. The auxiliary circuit is composed of two cap...
