摘　　要：在移相全桥ZVZCS PWM变换器基本原理的基础上,对其拓扑结构进行了改进,实现了一种带双变压器结构的零电压零电流移相全桥PWM控制变换器。论述了该变换器的工作时序和工作状态,给出了各个状态的等效电路。在拓扑结构基础上,调试出一台样机,并列出了实验波形。The topology structure is modified on the basis of basic principle of phase shift fullbridge ZVZCS PWM converter. A ZVZCS phase shift full bridge PWM converter with the two- transformer structure has been presented. The operation, analysis and features are illustrated. A prototype converter based on the presented to- pology has been built up. Experimental waveforms have been presented.
