روش جديدي براي مدولاسيون فضاي برداري در مولد هارمونيكي سه فاز

In three-phase convereters, space vector modulation (SVM) method can produce sinusoidal phase voltages with an amplitude of up to 15% greater than those produced by sinusoidal PWM. In this paper, a three dimensional model of SVM is investigated. Then, a new method is proposed to improve the shape of the phase voltage and minimizing the switching frequency. The new scheme is verified using a PC-based three-phase harmoic generator and the results are presented.
