一种抑制双并联三相功率变换器零序和相内环流的统一方法

This article proposes a unified pulsewidth modulation (PWM) strategy for suppressing both intraphase and zero-sequence circulating currents in two-parallel converters. The presented analytical modeling reveals that certain vector combinations inherently enable simultaneous control of both intraphase and zero-sequence circulating currents. Then, ten candidate vector sequences are constructed using ...
