Abstract
A variety of pulse width modulation strategies is now available for practical induction motor drive systems. Sophisticated 'optimum' techniques have been developed which may suppress specific low-order harmonics or optimize certain performance criteria. The effectiveness of these strategies in minimizing harmonic losses and reducing torque pulsations is investigated analytically, and their performance is compared with that of the more usual sinusoidal modulation technique. Fourier analysis is used to allow skin effect phenomena to be taken into consideration. A modified performance criterion is suggested which gives a more realistic indication of waveform quality in respect of harmonic losses.
