This paper proposes a fault-tolerant control strategy for T-type 3-level inverter systems. The proposed fault-tolerant strategy is

explained for two cases: the faulty condition of half-bridge switches and neutral-point switches. The performance of the T-type

inverter systems improves considerably by the proposed fault tolerant algorithm when a switch fails. The proposed method does

not require additional components and complex calculations. Simulation and experimental results verify the validity and feasibility of

the proposed fault diagnosis and fault-tolerant control strategy.
