Performance of a synchronous reluctance motor drive with a fault-tolerant three-level neutral point clamped inverter

This paper presents a performance analysis of a synchronous reluctance motor (SynRM) drive under different fault-tolerant modulation strategies. The analysis comprises different single power switches short-circuit faults in a three-level NPC converter controlled by a space vector modulation (SVM) technique. The comparison of the normal and two post-fault operating conditions is based on the analysis of certain parameters such as the motor efficiency, power factor, electromagnetic torque, currents RMS values, total waveform distortion values, and total waveform oscillation values, resulting from the computational simulations.
