| 摘 要： | 对于复杂的开关型功率变换器,其动态小信号模型的建立是一个很棘手的问题,本文提出了一种开关型功率变换器的建模方法——阶跃响应拟合法,并利用此方法建立了有源箝位推挽倍压变换器(Active Clamping Push-pull Dual Voltage Converter,ACPDC)的动态小信号模型。最后,采用建立的动态模型研究了该电路的闭环控制问题,并给出了仿真结果。

| Abstract: | It is very difficult for complicated switching power converter to build the dynamic small-signal model.A modeling method for switching power converter,which is called step-response fitting algorithm,was proposed in the paper, and the dynamic small-signal model of the Active Clamping Push-Pull Dual Voltage Converter was built using this method.Finally,the problem of closed-loop control for this converter was discussed on this model,and the simulation result was given. |
