ABSTRACT:
A high power motor drive converter includes a three level neutral point clamped (NPC) output power conversion stage including switches; a split series connected DC capacitor bank coupled in parallel with the NPC output power conversion stage; and a controller for selecting switch positions for controlling the NPC output power conversion stage and controlling a neutral voltage balance of the DC capacitor bank by using space vector modulation and predictive charge calculations.
