摘　　要：以半桥ZVS变换器作为研究对象,运用状态空间平均法建立小信号数学模型,设计了电流内环、电压外环双闭环反馈系统。用MATLAB软件自带的SISOTOOL工具箱设计电压电流PID传递函数的参数,可减少系统设计的复杂性。通过Matlab对实例进行分析,验证了设计的电流内环、电压外环双闭环反馈系统参数选择的合理性。In this paper, the phase shifted full bridge ZVSZCS converter as the research object, using the state space averaging method to establish the small signal mathematical model, the design of the current inner loop, volt-age outer loop double closed loop feedback system. MATLAB software with the SISOTOOL toolbox to design the pa-rameters of the voltage and current PID transfer function, can reduce the complexity of the system design. Through the analysis of Matlab, this paper verifies the rationality of the parameter selection of the current inner loop and voltage outer loop double loop feedback system.
