Performance evaluation of synchronous reluctance motor drives under inverter fault conditions

This paper presents a performance analysis of a synchronous reluctance motor (SynRM) drive under different faulty operating conditions. Considering the voltage source inverter, single power switch open-circuit faults and single phase open-circuit failures are introduced and their effects are analyzed regarding the performance evaluation of the SynRM. The comparison of normal and faulty operating conditions is based on the analysis of certain key parameters such as motor efficiency, power factor, electromagnetic torque, currents RMS values, total waveform distortion values, and total waveform oscillation values, resulting from the computational simulations.
