移相控制零电压开关 PWM 变换器的分析

Analysis of the Phaseshifting Controlled ZVS PWM Converter

分析了移相控制零电压开关ＰＷＭ变换器的工作原理，讨论了实现零电压开关的条件和策略，以及占空比丢失的原因，给出了仿真和实验结果。

The authors analyze the operation principle of the phaseshifting controlled ZVS PWM converter,discuss the conditions and strategies for realizing the ZVS and the reasons of the dutycycle lossing on the secondary.The simulating and experimental results are given.
