一种用于两台并联三相两电平功率变换器协同PWM方案的通用低频零序环流抑制方法

This article addresses the challenge of mitigating low-frequency circulating currents caused by imbalanced inductance while preserving the inherent benefits of coordinated pulsewidth modulation (PWM) schemes. The analysis reveals that traditional common-mode injection is incompatible with the coordinated PWM schemes. To resolve this, this article proposes a general approach to suppress the low-fre...
