交-交电力变换器拓扑结构综述

摘要

The AC-DC-AC converter and the direct matrix converter both have a large number switches and their commutation processes are complicated.To address this problem,this paper introduces some new matrix converter circuit topologies with their working principles and control modes.These topologies are compared with the direct matrix converter,and the advantages and disadvantages of the new matrix converters are obtained,which lays some foundation for the application of the matrix converter in the power system.%为了解决交-直-交型变换器和直接型矩阵式变换器中存在的开关数量多、换流过程复杂的问题,详细地介绍了一些新型矩阵式变换器电路拓扑及其工作原理和控制方式,并将其与直接型矩阵式变换器进行比较,从而得出各式新型矩阵式变换器的优缺点,为后续矩阵式变换器在电力系统的应用奠定基础.
