摘　　要：本文深入分析了移相全桥零电压(ZVS)PWM变换器的工作原理,并给出电路关键参数设计依据。在此基础上,采用移相全桥零电压(ZVS)PWM变换器设计了一台用于电力系统壁挂开关电源的实验机。实验结果表明设计的样机性能优良,运行稳定可靠,有良好的工程应用推广价值。The deep analysis on the principle of phase - shift full bridge zero - yohage - switching（ PS - FB - ZVS） PWM converter was made, and the basis for designing the main parameters of this topology was also given. On this foundation, this thesis designs an experimental prototype of wall - mounted switch power supply that applied to electrical power systems. The experimental results demonstrate that the prototype has excellent performance, works stably and reliably, and it also has high value on engineering application and promotion.
