一种基于两电平共模电压抑制PWM的三电平中点钳位逆变器改进简化PWM

In this article, a common-mode voltage reduction pulsewidth modulation (CMV-R PWM) for three-level neutral point clamped inverter based on the simplification of the three-level space-vector diagram into that of a two-level inverter is studied. By replacing the switching sequence of two-level space-vector PWM with that of CMV-R PWM, the common-mode voltage of the proposed method can be restricted t...
