Harmonic Elimination In Nine Level Inverter By Imperialist Competitive Algorithm

Abstract

This paper presents the solutions of Selective Harmonic Elimination problem based on an imperialist competitive algorithm. This method for eliminating harmonics particularly predetermined harmonics of the 9-level inverter. Minimize the harmonic is the difficult problems because of the nonlinear transcendental equations is ordered to find out the switching angles, controlling inverter output voltage and also minimized Total Harmonic Distortion of output voltage.. The proposed method is able to eliminate the high number of predetermine harmonics. Simulation work is achieved by using the MATLAB software which verifies the proposed method and finally Total Harmonic Distortion comparison is presented for analysis.
