Abstract :
This paper proposes two new strategies for control of three-phase voltage source inverter with pulse-width modulation. Their feature is modification of carrier frequency by predetermined law. The proposed methods are compared with scalar PWM and random PWM regarding to quality output voltage and current of voltage source inverter. The results of this comparative analysis are presented.
