摘　　要：从传输机制说明单管升降压变换器(如Buck-Boost、SPEIC、Cuk)中元件承受的电压和电流应力高的原因,并根据这一机制,采用变换器合成的方式,提出了一系列的双管Buck-Boost变换器。这类变换器根据输入输出条件,可以分别工作于Boost模式和Buck模式,起到降低元件应力的作用。Using the transmission mechanism, it can be konwed why single-switch step-up/step-down converters, such as the buck-boost, SEPIC and Cuk, have high voltage and current stresses on components. Base on the tramsimssion mechanism , using the converter synthesis mothod, families of double-switching buck-boost converters are generated, including several new converter topologies. The buck-boost converter with two independently controlled switches can work as a boost or as a buck converter depending on input-output conditions, and thus achieves lower stresses on components.
