- Abstract
- This paper proposes a novel method to reduce the switching loss in a single-phase flying-capacitor multilevel inverter. The proposed method satisfies the regulation of a flying-capacitor's voltage and also reduces the switching loss. The proposed method is based on the redundant state selection (RSS) method, reported as the solution for a control of the flying-capacitor's voltage. The modified RSS criterion considers the switching state transient for minimizing the switching loss. The theoretical analysis and detail implementation of the proposed approach are presented. Through simulation results, the effectiveness of the proposed RSS method is verified.
