| 摘 要： | 系统地提出PWMDC/DC全桥变换器的一族共9种控制方式，根据斜对角的两只开关管的关断情况，将这九种控制方式归纳出两类开关切换方式。引入超前桥臂和滞后桥臂的概念，提出PWMDC/DC全桥变换器软开关的实现原则。

| Abstract: | This paper proposes a family of control modes including nine control modes which can be classified into two kinds according to the turn off subsequence of the two power switches in the oblique diagonal line of the two bridge arms. The concept of leading arm and lagging arm is introduced to realizes soft switching for pwm dc/dc full bridge converters. The realization of soft switching for both leading and lagging arms is proposed also |
