Abstract
Induction motor was very often used machine in industries. Recent developments in electronics led to use of induction motor-driven electrical vehicles. Faults in inverter-fed induction motor can lead to unusual operation. The knowledge of faults in inverter circuit is as important. Fault identification is as much important as prior knowledge to mitigate the faults that might occur in inverter-driven induction motor drives. In this paper, five-level multi-level inverter was taken up for testing of mitigation using redundant cell. In this simulation model only two fault cases are considered for voltage source inverter (VSI)-fed squirrel cage induction motor drive. Those two cases are switch open fault and switch short fault. In this work redundant cell comes into operation when switch is open fault, short fault in drive system. The Matlab/Simulink-based model clearly explains the effect of adding redundant cell during fault.
