Abstract:

本文提出了一种基于Boost拓扑与Cuk拓扑有机组合思路的适用于LED照明系统中的组合式Boost-Cuk变换器,Boost环节与Cuk环节共用输入支路,使该变换器通过一个开关管同时实现两路输出,一路输出为Boost型,另一路输出为Cuk型。Boost环节与Cuk环节的输出串联,提高了该变换器的输出电压增益。为了灵活控制输出,只需一个控制器便可以实现多种方式的输出。仿真结果证明该拓扑结构性能与理论分析一致。
A Combined-type Boost-Cuk converter for LED lighting system was proposed based on the combi-nation of Boost and Cuk topologies. The converter using a switch can simultaneously achieve two kinds of output by sharing the branch of the input side of the two topologies mentioned. One of the outputs for the converter is Boost-type, and the other one is the Cuk-type. The voltage gain of the converter is improved with the output of Boost and Cuk topologies proposed in series connected. In order to control the output, only one controller can achieve the output in various ways. The si-mulation results are given to verify the consistence between the performance and theoretical analysis of the topology.
