Performance Improvement of a Single Phase Induction Motor Fed by Nonsinusoidal Voltages


The distorted voltage waveforms, which have, more or less, a high harmoniccontent, have negative impact on the long-term performance of the motor, as theycause nonsinusoidal currents in the stator and the rotor, and consequently additionallosses and distorted torque in the machine.The steady state performance of Permanent Capacitor single phase inductionmotor fed by optimal SHEPWM inverter is studied with respect to harmonics,additional losses and torque pulsations. The effectiveness of the optimal SHPWMtechnique in improving of motor performance is investigated analytically
