Abstract

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 inverters output voltage is controlled by PWM from the input DC voltage. The complex Fourier series analysis of the inverter output voltage was made, in order a spectrum of the harmonic supply voltages. The different voltage harmonics have been applied to the three-phase induction machine mathematical model to obtain electromagnetic torque and supply current waveforms for various operation states.
