| 摘 要： | 为提高开关电源效率，在对全桥移相PWM（FB－PWM）变换器工作原理及其工作状态分析的基础上，介绍了FB－PWM变换器实现零电压转换的条件，并提出以能量和时间两个概念分析的方法，利用集成控制芯片ML4818作为移相控制核心设计了零电压转换的FB－PWM（ZVS FB－PWM）变换器，并完成了实验，结果证明分析和设计是正确的。

| Abstract: | In order to improve switch power efficiency and based on the analysis of the working principle of full bridge phase shift PWM(FB PWM) converter and its working conditions, this paper describes the conditions for FB PWM converter to achieve ZVS and suggests the analytical method based on two concepts of energy and time. A ZVS FB PWM converter is designed by using integrated chip ML4818 as the core of phase shift control with the experiments completed, whose results have proved the correctness of the analysis and design. |
