Abstract :
The contribution deals with steady state estimation of a electromagnetic torque ripples and a current waveform of a two-phase induction motor, which is supplied by an three-leg IGBT bridge connected inverter. The inverter´s output voltage is controlled by a modified sinusoidal SPWM 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 voltage. The different voltage harmonics have been applied to the two-phase induction machine model to obtain electromagnetic torque and supply current waveforms for various operation states.
