This paper proposes a new strategy for balancing the neutral point voltage in the process of the three-level inverter vector controlling.
本文主要研究三电平逆变器在电压空间矢量控制过程中中性点电压平衡的控制方法。
Meanwhile, the topology has voltage-self-balance ability, and therefore, no additional neutral-point-potential balancing circuit is needed.
同时，该拓扑具有电压自平衡能力，无需额外的中点电位平衡电路。
