Abstract
The purpose of this research is to present analysis of the harmonic content present in the phase current of a three phase induction motor while being powered by a voltage source pulse-width modulated (PWM) variable speed drive (VSD). First, the topology and circuit of the drive, its operational fundamentals and waveform appearance are presented and discussed. Next, the three-phase induction motor circuit model and operational characteristics are discussed. Finally, the harmonic content present in the induction motor phase current is determined by use of the PSPICE model. The ability of the PSICE simulation to determine harmonic content is established. It is shown through the use of voltage and current waveforms and tabulated data that the harmonic current present in the induction motor stator windings is a function of various key aspects of the PWM inverter and the motor. No particular generalization regarding the harmonic content can be assigned to three phase induction motors under voltage source pulse-width modulated power.
