Abstract:
Methods and charging apparatus are presented for charging cell capacitors of a multilevel power conversion system, in which an auxiliary charging source is selectively applied across DC bus terminals while one or more selected multilevel converter cells are alternately switched between a first state to bypass the selected cell or cells and a second state to charge the cell capacitor or capacitors of the selected cell via charging current from the auxiliary charging source.
