基于扩展换流单元的八电平DC-AC变换器负载电流校正电容电压控制

The extended commutation cell is a four-port four-switch cell that allows for bidirectional energy transport in two orthogonal directions throughout the cell. By cascading multiple cells, a multilevel converter can be constructed with a high number of levels. The voltage across each cell capacitor can be adjusted independently of the load, resulting in high flexibility in output levels. This paper...
