摘　　要：提出了一种能在全负载范围内实现零电压开关的改进型全桥移相ZVS—PWMDC／DC变换器．该电路简单高效，超前臂、滞后臂都能在很宽的范围实现软开关．介绍和分析了变换器的工作原理，最后给出了实验结果和两个主要波形，并做出了详细的说明．An improved full bridge phase-shift ZVS-PWM DC/DC converter which can achieve ZVS in the range of any load condition is introduced. The converter is simple and efficient, and the lagging-leg as well as the leading-leg can achieve soft switch in a very broad range of loads. The operation principle of the con- verter is explained. At last, the experiment results and waveforms are presented and explored in detail.
