摘要

基本的转换器(降压、升压和降压-升压)通过改变散装电容器的位置来修改。电容器连接在输入和输出之间，而不是与输出连接器平行。通过绘制信号图对三种改进型变换器结构进行了分析，并推导出电压变化率。仿真结果验证了基本分析的正确性。通过附加电路消除了不连续模式下的典型振铃现象，仿真结果表明了该方法的有效性。

Modified Basic Converters in the Discontinuous Mode

The basic converters (Buck, Boost, and Buck-Boost) are modified by a change of the position of the bulk capacitor. The capacitor is connected between the input and the output and not parallel to the output connectors. The three modified converter structures are analyzed by drawing the signal graphs, and the voltage transformation rate is derived. Simulation results are shown to verify the basic analyzes. The typical ringing in the discontinuous mode is than canceled with an additional circuit and simulation results show the effectiveness.
