Paper Title
Fault Diagnosis Of VSI-FED Three-Phase Induction Motor

This paper aims at developing an efficient tool for the fault diagnosis of VSI-fed 3-phase Induction motor. The considered faults include stator winding faults of the induction motor and open power switch faults in the voltage source inverter. Any single phasing situation creates the stator fault that may result in opening of one or more phase windings. In this work, the induction motor model is modified for analyzing the open circuit fault of the stator phase winding and the current patterns obtained using Park’s Vector Approach are compared. The power switch faults in the converter are analyzed using Normalized Currents Average Values method.
