一种针对直流侧电压不平衡的五电平飞跨电容整流器多零序分量注入算法

In this article, the mechanism of current distortions for a five-level flying capacitor rectifier under unbalanced dc-link voltages is analyzed in detail. A multizero-sequence component injection algorithm based on phase-shifted pulsewidth modulation is proposed. In specific, the proposed modulation algorithm divides the fundamental period into clamping and continuous intervals. Considering the in...
