Leong, CY and Grinberg, R and Makrides, G and Wu, Y and McMahon, RA (2005) A comparison of losses in small (<1 kW) drives using sine and space vector pulse width modulation schemes. Proceedings of the International Conference on Power Electronics and Drive Systems, 2. pp. 1123-1128.Full text not available from this repository.
this paper quantifies effects of using three different pulse width modulation (PWM) schemes on the losses in the inverter and induction motor of a 1 kW drive. Direct measurements of losses have been made with a calorimeter. Results show that for the inverter, discontinuous PWM excitation reduces losses by up to 15% compared to sine and symmetrical space vector PWM methods. However, at a low modulation index the greater harmonic content with discontinuous PWM increased motor losses by nearly 20%. This study demonstrates the importance of careful choice of modulation scheme to achieve high overall drive efficiency. © 2005 IEEE.
