摘要
采用平均开关模型方法建立了不连续导电模式(DCM)V2C控制Boost变换器的小信号模型,得到了相应的交流小信号传递函数,并对DCM模式V2C控制、电流型控制和电压型控制Boost变换器进行了仿真研究。分析和仿真表明在DCM模式下V2C控制方法比电流型控制方法具有更好的动态响应特性。
The paper deduces the V^2C controlled Boost converter in discontinuous conduction mode （DC M） by using averaging model of PWM switch. The output impedance, input-to-output and control-to-output transfer functions are derived. The frequency domain simulation of V^2C controlled, current mode controlled and voltage mode controlled Boost converters in DC M are performed separately and the results of which are analyzed and compared with each others. It shows that the dynamic characteristic of the V^2C control is better than that of current mode control and voltage mode control in DCM.
