Abstract :
This paper presents the results of an experimental investigation regarding the performance of a three-phase induction motor fed by a three-level neutral-point-clamped converter with fault tolerant control strategies. A discussion about the fault diagnostic method used in this work, together with the used fault tolerant control strategy is presented. Experimental results regarding the thermal, electrical and mechanical behavior of a three-phase induction machine as well as the global efficiency of the ac drive under inverter normal and post-fault reconfiguration operations are discussed.
