  1. This paper focuses on the control strategies to improve the performance of the three - phase ac - dc pwm voltage - source - converters ( vsr ) under unbalanced power supply. the problems such as negative sequences current, voltage and current harmonics and un - constant ( un - smooth ) power flow from ac to dc side are discussed in this paper. the analytical solutions for negative sequence current and harmonic current elimination are obtained by fully feed - forward of negative sequence voltage and producing a non - harmonic current command of the inner - loop

    電網不平衡,基於電網平衡為約條件設計的三相vsr將出現不正常運行狀態,比如三相vsr交中出現負序分量,使交嚴重不對稱;直電壓和交中出現非特徵諧波分量,使直電壓和交波形發生嚴重畸變;三相vsr從電網吸收不平衡的功率等一系列問題。
