基于最优空间矢量调制的背靠背电流源变换器共模电压抑制

Common-mode voltage (CMV) problem is one of the most important issues for back-to-back current-source converters. In this paper, the theoretical analysis is presented to clarify that the system CMV mainly depends on the CMV difference between a rectifier and an inverter. And then, a new CMV mitigation technique is proposed. Different from the existing methods, the proposed method coordinates the a...
