Abstract

Induction motors are used extensively in a wide variety of industrial applications. The development in the power electronics field have led to an ever- increasing use of thyristors switching devices in the induction motors supply voltage control for the purpose of speed control, soft starting, and energy saving in these applications. Such power electronics switching devices generate different waveforms patterns of nonsinusoidal voltage according to balanced and unbalanced condition of their operation. So, the present paper investigates the impact of this nonsinusoidal supply voltage waveforms on the dynamic performance of a three-phase induction motor during balanced and unbalanced operation. Also, this paper considers the IM operation at different loading conditions. A MATLAB program has been used to model the thyristorized induction motor performance.
