T型三电平逆变器的容错控制策略可靠性提升研究

This paper proposes a fault-tolerant control strategy for a T-type three-level inverter when an open-circuit fault occurs. The proposed method is explained by dividing fault into two cases: the faulty condition of half-bridge switches and neutral-point switches. In case of the open-circuit fault in a neutral-point switch, two methods will be proposed and compared based on thermal analysis and neut...
