Abstract :
In this paper, a novel fault detection method based on cost fault evaluation is proposed. The cost function is same as one used in finite control set model predictive control of power converters. Two simple methods are presented to locate the faulty IGBT. Considered methodology is studied for fault detection and fault tolerant operation in a five phase PMSM drive. Theory has been developed and validated by simulation results of a five phase two level converter in Matlab/Simulink.
