摘　　要：ZVZCS移相全桥PWM变换器实现了超前桥臂零电压开关(ZVS)和滞后桥臂零电流开关(ZCS),具有结构简单、占空比丢失较小、软开关较容易实现等特点。文章全面分析了该变换器的工作原理、讨论实现软开关的条件,设计了主要参数,然后利用SIMetrix仿真软件对电路进行仿真,通过波形验证了参数设计合理、变换器实现ZVZCS。The ZVZCS phase-shifting full bridge PWM converter achieves ZVS of the leading-leg and ZCS of the lagging-leg, which structure is simple, duty cycle loss is small, soft switching is easy to implement and so on. This paper analyzes its principle from all around, discusses the condition of achieving soft switching, designs main parameters and simulates it by using SIMetrix software. The results prove that parameters are designed reasonably and this converter can achieves ZVZCS.
