摘要
基于SEPIC拓扑结构,分析其工作原理,通过状态空间平均法,得到该变换器的动态小信号模型,讨论了其占空比与稳定性之间的关系,并在宽幅压输入条件下对其各元件参数进行了优化选取,并通过Matlab软件仿真加以分析,从而得出结论,具有独具特色优点的SEPIC变换器是船用幅压直流变换器的方案选择之一。
Based on a SEPIC topology,the work principle is analyzed.A leads to a small-signal linear model of the converter using the State-Space Averaging method,the relation of the duty cycle and the stability is discussed.Finally the parameters of the elements are selected well in a wide input voltage by a simulation test.The result shows that the SEPIC converter is the one of the DC-DC converter in a wide range voltage input of the ship’s light substation.
