A.C. ELECTRIC DRIVE WITH PULSE-WIDTH MODULATION CONTROL

Abstract

The paper proposes an original method for pulse-width modulation (PWM) of A.C. voltage. The method makes it possible to improve harmonic composition of the voltage. The paper presents results of approbation of the method for PWM-control of an asynchronous electric drive using the developed model in the environment of МathCad.
