This paper presents a three-phase three-level quasi-Z-source inverter (qZSI) topology that can be operated in normal and fault tolerant operation modes. The presented structure is a combination of two symmetrical quasi-Z source networks and T-type inverter. The proposed topology has characterized by their semiconductor fault tolerance capability. This feature is only obtained by additional extra phase legs. In addition, the qZSI overcomes the issues of shoot-through (ST) mode and operating in normal and failure mode. The effectiveness of proposed inverter topology and control methods is validated by the simulation results.
