Optimization of Harmonics in Novel Multilevel Inverter using Black Wolf and Whale Optimization algorithms

Abstract

High-quality electrical energy is the most needed thing for standard living. We use power electronics converters for the conversion of different forms of electrical energy and we use them for producing quality power output. We use semiconductor devices as switches in the process of conversion of DC-DC, AC-DC, AC-AC, and DC-AC according to the requirement of the system. In this paper, an attempt is made to analyze the quality of output power from a multilevel inverter which is used in the conversion of DC supply to AC output voltage. Production of quality power by optimizing the multilevel inverter switching using Whale Optimization Algorithm helps the proposed inverter topology to perform well. The suggested topology and the optimization technique will help in harvesting multiple renewable energy sources with improved quality of power. Different DC sources of different voltage levels could be connected in input and the resultant AC output has less ripple content as per the IEEE standard. A detailed comparison has been made to show the superiority of the proposed algorithm.
