摘要：
An interleaved resonant flyback converter with zero-voltage-zero-current-switching (ZVZCS) operation is proposed. The proposed converter consists of two identical resonant flyback converters. It features zero-voltage-switching (ZVS) operation of active switches and zero-current-switching (ZCS) operation of output rectifying diodes. Consequently, the reverse-recovery loss on the output rectifying diodes is significantly reduced. Moreover, ZVZCS characteristic of the proposed converter reduces the switching losses and raises the overall efficiency. Experimental results based on a 90 W (120V / 0.75A) prototype are provided to verify the effectiveness and feasibility of the proposed converter.
