一种隔离型DC/AC矩阵变换器的容错切换方案

A fault-tolerant scheme is proposed for a multistage isolated three-phase dc/ac matrix inverter (MI-TMI). It comprises a front-end dc/ac converter followed by an ac/pulsating-dc converter and a pulsating-dc/ac converter. The fault-tolerant scheme (FTS) ensures a consistent operation under different fault conditions in any of the three stages of the TMI mentioned previously. A fault-diagnosis schem...
