针对两台并联交错三相变换器的零序环流抑制及线电流纹波最小化PWM策略

This article proposes a line-current ripple minimization pulsewidth modulation strategy with reduced zero-sequence circulating current (ZSCC) for two parallel three-phase two-level converters. We split each 60° sector into six subsectors, each applies the nearest three vectors to ensure minimal line-current ripple. To reduce the ZSCC, we further investigate all vector sequences of the nearest thre...
