矩阵式变换器安全换流策略研究

Study on A Reliable Method of Current Commutation in Matrix Converter

本文对矩阵式变换器的开关换流进行分析,论述了四步换流策略的正确性和可靠性,并通过复杂可编程逻辑器件(CPLD)加以实现。仿真和实验结果表明四步换流策略可以使矩阵变换器中的双向开关换流安全可靠地进行。

This paper discusses the current communication between switches in matrix converters. Reliability and validity of fourstep commutation strategy is proved. The four-step commutation strategy is implemented by CPLD.simulation, and the result of experiment prove that four-step commutation method proper and reliable.
