Abstract

A new soft-switching flyback converter with  coupled inductors  snubber is presented in this paper. The passive snubber circuit, which is composed of two diodes, two capacitors, and two coupled inductor, ensures a zero current turn-on and zero voltage turn-off conditions for the power switch, and alleviates the reverse-recovery problem for the output diode. Moreover, with the proper design of the snubber circuit, the power switch and output diode can be softly switched in a wide load range. The operating principle and performance analysis of the proposed converter are described in detail. The experiment from a 400W prototype has been carried out and the results show that the proposed converter has the advantages of simple structure, low complexity control, and the highest efficiency is more than 95%.
