摘　　要：针对全桥零电压零电流变换器引入了变压器副边有效占空比的概念,并且在BUCK变换器的开关等效模型基础上建立了ZVZCS全桥变换器的小信号等效模型,通过所建模型,提出建立电压外环电流内环的分数阶PID控制方案,仿真验证了控制方案的正确性。最后仿真验证了建模的合理性和双环控制的有效性。By introducing the effective duty cycle of the transformer＇s secondary side voltage, and basing on the switching equivalent model of BUCK converter, the small-signal equivalent model of ZVZCS full-bridge converter was established. Through the model, the outer voltage inner current loop fractional-order PID control was established; finally, the simulink was used to verify the rationality of that model and the effectiveness of the double loop controller.
