摘　　要：介绍了滞后桥臂串联二极管的全桥零电压零电流变换器的结构,分析了其工作原理,并利用小信号模型分析方法建立了数学模型,在此模型基础上提出了该全桥零电压零电流变换器的电压电流双环控制策略,最后给出了在MATLAB/SIMULINK仿真环境下应用该控制方案的仿真结果。The topology and operating pinciple of ZVZCS Full-Bridge Converter with two diodes in series with the lagging leg was presented.And the mathematical model of the converter based on the small signal analysis method was also introduced in this paper.Based on the mathematical model,a voltage and current double loop control scheme was established,which was similar with the control scheme of the DC motor.And at the last,some simulation results by the MATLAB/SIMULINK tools were presented.
