摘　　要：对移相全桥零电压零电流开关(Zero-Voltage and Zero-Current Switch,ZVZCS)变换器数学模型进行深入分析,提出用专家系统PID控制器实现对变换器开关管导通相序和占空比的改变。详细介绍了移相全桥ZVZCS变换器的拓扑结构、工作模态、小信号模型推导以及专家系统PID的设计规则,最后用Simulink仿真验证了算法的正确性和可行性,并对结果进行了分析讨论。Based on the phase shifted full bridge zero voltage and zero current switching（ Zero-Voltage and Zero-Current Switch, ZVZCS ） converter mathematical model to carry on the analysis, this paper proposed the expert system PID controller to realize the conduction phase and duty ratio on the converter switch. It introduces the phase shifted full bridge ZVZCS converter topology, working mode, small signal model derived and expert system PID design rules. Finally the correctness and feasibility of the algorithm are verified by Simulink simulation, and the results are discussed on and analyzed.
