不平衡电网电压下三相双向电流源变换器注入平衡三相电流的控制

A single-stage, bidirectional, current-source converter (CSC) topology to interface a dc microgrid with an ac grid is reported in the literature. In this topology, under a balanced grid voltage condition, the dc-link inductor current can be regulated over a wide range-from zero to rated value-while the ac-side current has low harmonic distortion. However, unbalanced grid voltages result in second-...
