一种抑制频率变化的谐振正激-反激变换器方案

This letter proposes a simple and low-cost scheme to soft switch an isolated converter. The new circuit merges resonant forward converters and flyback converters by using shared power transformers and primary switches. Specifically, the resonant forward mode operation fulfills soft-switching for the primary switches, and the flyback mode operation resets the transformers by directly delivering the...
