The paper deals with steady state analysis of electromagnetic torque ripples of a three-phase induction machine, which is supplied by an IGBT transistors bridge connected inverter. The inverter’s output voltage is controlled by a PWM of the input DC voltage. The complex Fourier series analysis of the inverter’s output voltage was made, to obtain a spectrum of the harmonic supply voltages. The different voltage harmonic was applied to the two-phase asynchronous machine model to obtain the electromagnetic torque waveforms for various operation conditions.
