Single-switch Converter with Composite Topology Based on Coupled-inductor Voltage-doubling Technology
摘要
Abstract
To solve the bottleneck problems of insufficient voltage gain and efficiency limitations in DC/DC converters under high-voltage application scenarios,a DC/DC converter with a novel composite topology based on the coupled-inductor voltage-doubling technology is proposed in this paper.Under this scheme,the advantages of Boost and Sepic circuit structures are integrated,a coupled-inductor voltage-doubling unit and a passive clamping network are intro-duced,and a current-input architecture is built.Moreover,this scheme can achieve leakage inductance energy reco-very and zero-current switching of all the switching devices while ensuring continuous input current.The working princi-ple for the converter is analyzed in detail,and its performance parameters and critical conditions in continuous conduc-tion mode are given.Results show that the novel topology has advantages of high voltage gain and low voltage stress.In addition,a 200 W prototype was built to verify the high-efficiency operating characteristics of the converter,which also effectively proves the accuracy of the theoretical analysis.关键词
