中文摘要

针对电机驱动应用中辅助谐振换相极(ARCP)逆变器直流侧电容中点电压波动导致软开关失效及损耗增加的问题,本文提出了一种基于谐振电流调节的新型中点电压平衡控制策略,有效消除了中点电压波动。

English Abstract

The auxiliary resonant commutated pole (ARCP) inverter with dc-link divider capacitors has the midpoint voltage fluctuation in the motor drive application since the fundamental frequency starts at zero. This problem leads to incomplete soft-switching and additional losses. In this article, a novel midpoint voltage balance control strategy is proposed to eliminate the midpoint voltage fluctuation o...
