Abstract:- The paper presents the fault tolerant three-phase ac motor drive topologies that have been proposed to provide output capacity for the inverter faults in some of the power switches. Such a system uses two distinct space-vector modulation strategies to switch from healthy to the faulty operation. The analytical investigation both in time and frequency domain is proposed. As demonstrated by the experiments there are good agreement between the analytically calculated and the experimentally determined ones.
