Abstract

Selective Harmonic Elimination Pulse Width Modulation (SHEPWM) technique is one of the control techniques for inverters. It is mainly used for reducing the harmonic content in single phase and three phase inverters and to improve the power quality. The selection of switching angles for eliminating particular harmonic is difficult. The proposed method uses one of the soft computing techniques Genetic Algorithm (GA) to optimize the switching angle given to the single phase and three phase inverters. The bipolar waveform includes both odd and even number of switching angles to eliminate particular harmonics (5th, 7th, 11th and 13th) from inverter output. Elimination of selected harmonics is verified using MATLAB simulation for both single and three phase inverters. Optimized SHEPWM technique for three phase inverter is compared with standard PWM method using MATLAB simulation and results are presented.
