Diode-clamped converters (DCCs) suffer from the inherent capacitor voltage imbalance problem. Most software-based voltage-balancing methods fall into the space vector modulation category and the carrier-based pulsewidth modulation category. Despite their effectiveness for the three-level DCCs, it is...
