【Abstract】 A novel multiplex forward converter is described in this paper.A snubber capacitance is used to replace the conventional reset winding of high-frequency transformer.Therefore,the design of high-frequency transformer is predi-gested.At the same time,this design absorbs the voltage stress in power switching very well.This paper particularly ana-lyzes the principle and characteristic of this complex forward converter.Finally,the excellence of this multiplex forward converter is verified by experiment.更多还原
