摘要
Abstract
The high frequency circulating current caused by asynchronous carriers is studied emphatically prior to an analysis of the circulating current.The mathematical model of high frequency circulating current in the switching cycle is proposed.The carrier synchronization is realized according to the high frequency circulating current characteristics in a switching cycle,with the high frequency circulating current amplitude limited within a definite range.Finally,the experimental setup of parallel converters is built in the laboratory to verify the feasibility and effectiveness of the method proposed.关键词
