IMPROVING VOLTAGE REGULATION AND ELIMINATION OF HARMONICS IN PWM AC CHOPPER USING ARTIFICIAL INTELLIGENT TECHNIQUE

Abstract This paper proposes a harmonic reduction approach and output voltage regulation in pulse width modulation (PWM) based AC Chopper using artificial intelligent technique. The optimal switching angles are provided by artificial intelligent technique to minimize harmonic distortions. In addition, the simulation results are correlated to confirm the performance in terms of power factor by improving the power quality. It can be applied to design optimal switching patterns for other power converter topologies
