Comparative study of conventional SVPWM algorithms in terms of producing harmonics and the effect of the harmonics on induction motor

This paper focuses mainly on the effect of various voltage-source inverter modulation techniques on induction motor using space vector pulse width modulation (PWM). The comparative study is done on the frequency spectrum of machine's major parameters waveform. Thus, four different algorithms are evaluated for PWM of space vectors: conventional continuous PWM with active vectors each of which is centered in half-cycle, non-continuous 30-degree, 60-degree, and 120-degree modulations. Finally, simulations are carried out for the comparison of aforementioned algorithms considering harmonic production in main parameters of the induction machine.
