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