基于锯齿波载波PWM的降低开关损耗的多电平变换器共模电压消除技术

This article proposes an asymmetrical switching pattern to eliminate common-mode voltage (CMV) in multilevel converters while reducing switching loss by rearranging the switching sequence to minimize the number of level-shifts. In contrast to the existing symmetrical switching pattern, this approach achieves CMV elimination without increasing switching loss. To implement this asymmetrical switchin...
