| 摘 要： | 有源箝位正激(FAC)拓扑在中小功率DC/DC模块电源中具有广泛的应用,其中的Boost型FAC由于辅助开关管驱动无需隔离,因此更为简单可靠,易于实现.根据状态空间平均法对峰值电流控制的Boost型FAC变换器建立了交流小信号模型,得到电路的交流小信号状态方程及等效电路图,并由此推导出电路的开环传递函数.通过将电流内环...

| Abstract: | Active clamp forward(FAC) converter is widely used in small and medium sized power DC/DC module converters.Especially,the Boost type FAC is simpler,safer and easier to be realized,because the auxiliary switch dose not need an isolated gate drive signal.A small signal model of Boost type FAC converter is built by state-space averaging approach,and an AC small-signal state equation and an equivalent circuit are obtained.Therefore,the open-loop transfer functions of the entire circuit are presented.Then the am... |
