摘要
不带隔离变压器的DC-DC开关型功率变换器基本电路有Buck,Boost,Buck-Boost,Cuk,SEPIC和Zeta六种,其中有三对是相互对偶的;带变压器的基本电路有五种:Forward,Flyback,Cuk,SEPIC和Zeta。文中重点介绍SEPIC和Zeta开关变换器的基本性质及特点、开关变换器基本电路中的等效和对偶关系。
There are six basic topologies of DC-DC transformer-less switching-mode power converters, namely: Buck,Boost, Buck-Boost, Cuk, SEPIC and Zeta converters, three pair of which are dual each other,and five basic topologies with transformers: Forward, Flyback, isolated Cuk, SEPIC and Zeta converters. The basic performances and characteristics of the SEPIC and Zeta converters, and the equivalent and dual relationships in basic topologies of the DC-DC power converters are mainly introduced.
