This paper presents an efficient and reliable Evolutionary Algorithm based solution for Selective Harmonic Elimination (SHE) switching pattern. This method eliminates considerable amount of lower order line voltage harmonics in Pulse Width Modulation (PWM) inverter. Determination of pulse pattern for the elimination of some lower order harmonics of a PWM inverter necessitates solving a system of nonlinear transcendental equations. Imperialist Competitive Algorithm is used to solve nonlinear transcendental equations for PWM-SHE. Several methods are available to eliminate the higher order harmonics and it can be easily removed. But the greatest challenge is to eliminate the lower order harmonics and this is successfully achieved using Imperialist Competitive Algorithm without using transformer. Simulations using MATLAB are carried out to validate the solution and are compared with the Genetic Algorithm. The results show that the harmonics up to 13th were totally eliminated.
