Detection and compensation of switch faults in a three level inverter

This paper deals with open and short-circuit switch faults in a three-level inverter feeding a three-phsse induction motor. It also investigates the fault compensation via topologies that are able to maintain the system operation for a period of time. Simulated and experimental results verify the feasibility of proposed strategies.
