Analysis of a Two-Phase Asynchronous Motor Supplied by a Two-Leg SPWM Controlled Inverter

Abstract:

The presented contribution deals with steady state analysis of a two-phase asynchronousmotor, which is supplied by an IGBT transistors half- bridge connected inverter. The inverter outputvoltage is controlled by a SPWM of the input DC voltage. The complex Fourier series analysis of theinverter output voltage was made, to obtain a spectrum of the harmonic supply voltage. The differentvoltage harmonics was applied to the two-phase induction machine model to obtain electromagnetictorque and supply current waveform for various operation states.
