摘要：
This paper introduced the topology and space vector modulation strategy of NPC three-level inverter. A method of judging the sector where the reference vector located is proposed. The cause of neutral-point potential unbalancing is analyzed. In order to solve neutral-point voltage balancing problem, a control method fully utilizing redundant voltage vectors is proposed. Simulation results verified the correctness and effectiveness of the proposed method.
