| 摘 要： | 为了优化设计双向直流变换器（BDC）的控制系统,对双向直流变换器进行了精确建模。选用带有输入和输出滤波电路的半桥式Buck/Boost变换器作为建模对象,分析了变换器的工作原理,采用状态空间平均法分别建立了大信号模型和小信号模型,并理论推导了各个扰动电量到输出电压扰动的传递函数。最后在Simulink下建立了半主动混合储能系统,验证了建模的正确性。

| Abstract: | In order to optimize the bidirectional DC-DC converter control system,an accurate modeling of bidirectional DC-DC converter is very important. This paper presented a half-bridge Buck / Boost converter with input and output filter circuits as the modeling object. The working principle of the converter was analyzed and large-signal model and small signal model were established by the state-space averaging method. A semi-active hybrid energy storage system（ HESS） was modeling in Simulink to test the small signal model of half-bridge converter. |
