一种具有无源辅助谐振电路的零电压零电流开关交错双管正激变换器

This article presents an interleaved two-switch forward dc/dc converter with zero-voltage and zero-current switching, which adopts a coupled inductor and a snubber capacitor. The proposed converter can realize soft operation for main power switches by using the coupled inductor, snubber capacitance, the leading switches' parallel capacitances, and the transformer leakage inductance. Compared with ...
