The advent of inverter power supplies has led to a growing interest in the analysis of induction motors fed from non-sinusoidal sources. Overwhelmingly analysis is based on frequency domain methods and the few excellent time domain analyses have been largely neglected. Frequency domain techniques have the merits of simplicity and clarity, all that is required of the user is a knowledge of fourier analysis and of steady state ac circuit theory. In contrast time domain techniques require familiarity with the generalized theory of electric machines and ordinary differential equations. However in return for the extra effort time domain analysis offers directly information on important matters such as input voltage and current waveforms and torque waveform which are only provided by complex and subtle extensions to the frequency domain methods. The familiarization of engineers over the last decade with state variable methods and the development of related computer subroutines has today made the application of time domain methods as easy and as accessible as the frequency domain methods. The paper reviews the applicable techniques and uses as examples a three-phase machine connected to voltage source and current source inverters.
