摘　　要：Buck(降压)型变换器是现代电力电子技术中一种常用的电能变换方法,主要用于计算机、精密仪器、通讯系统等高性能DC-DC直流开环电源之中,它是现代电能变换中的一种重要方法。结合典型的Buck变换器,采用状态空间平均法建立了主电路的小信号模型。A buck converter is a common electric energy changing method of modem electronic technique, which is mainly used in high-performance DC-DC open-loop power supply of computers, precision instrucments and communica- tion systems. It is an important method in modem electric energy change. Combine with typical Buck converter and use state-space average method to build the small signal model of the main circuit.
