具有五至八个输出电压电平的简化飞跨电容三单元逆变器的全范围运行

Compared with the conventional flying capacitor (FC) multicell converters, the simplified FCMC converter family has a significantly reduced number of FCs with a much higher power density. However, such simplification results in a limited number of redundant switching states, which makes the balancing of FC voltages a very challenging task that confines their valid operation range. In this article,...
