Abstract

Abstract This paper introduces harmonic removal in a Switched capacitor multilevel inverter utilizing artificial bee colony (ABC) method. The main focus is to neglect lower order harmonics by resolving nonlinear equation. In our paper, ABC algorithm is enforced to a twenty nine level inverter for resolving the equation. Selective Harmonics Elimination PWM is mainly used in lower order harmonics suppression. The MLI gets input from the SEPIC converter that comprises of Photo Voltaic Module as a source of generation. The PV panel output voltage is maintained constantly with a greater gain DC-DC SEPIC converter. Hence to obtain high power from the PV system, gray Wolf Optimization technique and fuzzy logic control is used. The high frequency modulation technique i.e. Multi Carrier modulation technique is too applied in the proposed new topology for reducing the higher order harmonics. The proposed ABC harmonics elimination technique is also compared with genetic algorithm based SHE method. MATLAB simulation platform is utilized to simulate the module. The experimental verification of the proposed work was done using DSPIC30F2010 controller.
