Inverter fed induction motors play a vital role in providing reliable operation in many industrial applications. However, the probability of failure of inverter switches is higher when compared to electro-mechanical systems. As the power electronic converter is the crucial unit in the drive, the failure of a semiconductor switch might lead to the failure of the entire drive. Therefore, it is an important concern to improve the fault-tolerance of the inverters to effectively utilize the induction motor drives (IMD). This paper proposes a reconfiguration of the nine-phase IMD to operate the system under the single-leg open-switch fault condition. ANSYS Maxwell is used for the FEM analysis of the nine-phase IMD under both normal as well as fault conditions.
