Wu, Y and McMahon, RA and Zhan, Y and Knight, AM (2006) Impact of PWM schemes on induction motor losses. Conference Record - IAS Annual Meeting (IEEE Industry Applications Society), 2. pp. 813-818. ISSN 0197-2618

This paper presents the results of an investigation into the impact of pulse width modulation (PWM) switching schemes on power losses in induction motors and their inverter drives. The PWM schemes considered include sinusoidal PWM, spacevector PWM and discontinuous PWM. Both experimental results and simulated predictions are presented for fractional horsepower and small integral horsepower motors. Direct loss measurements have been carried out using a calorimetric test rig; detailed simulations of the skewed motors have been carried out using multi-slice time-stepped 2D FEA. The simulated and measured losses under the different modulation schemes are compared and discussed. © 2006 IEEE.
