This paper examines the switch open circuit fault in a Pulse Width Modulated (PWM) Voltage Source Inverter (VSI) fed three phase induction motor (IM) using Finite Element Method (FEM). The analysis is based on the electromagnetic field parameter of the IM, when an IGBT switch in the PWM inverter leg...
