摘　　要：This paper proposes a family of PWM modulation strategies for boostfull-bridge (FB) converters. The modulation strategies can be classified into two kinds according tothe turn-on sequence of the diagonal switches. The concept of leading switches and lagging switchesis introduced to realize soft-switching. According to the soft-switching realized by the leadingswitches and the lagging switches, two kinds of soft-switching techniques for PWM boost FBconverters yield: zero-current-switching (ZCS) and zero-current and zero-voltage-switching (ZCZVS).Simulation results verify the analysis.本文系统提出boost全桥变换器的一族共 9种PWM控制方式 .根据一对斜对角开关管开通情况的不同 ,将这 9种PWM控制方式分成 2类切换方式 .为了实现软开关 ,引入超前管和滞后管的概念 .在此基础上 ,将软开关PWMboost全桥变换器分成ZCS和ZCZVS两类 .计算机仿真结果证实了所做的分析 .
