Design and Development of 7-Swithced Multilevel Inverter 15 Level Using Fuzzy Logic Algorithm

Abstract

Harmonics cause the power quality of solar photovoltaic (PV) energy conversion systems to deteriorate. In order to address this problem, this article looks into how Fuzzy Logic (FL)-based controllers can reduce harmonics in a solar system with a cascaded 15-level inverter. Recently, interest in multilevel inverters has grown as a result of their capacity to produce output waveforms of excellent quality at low switching frequencies. They are therefore incredibly desirable for high-power applications. By removing some of the lower order dominant harmonics, the output waveform's quality can be improved. It is suggested to use a modern multilayer inverter with fewer power switches. This novel cascaded H-bridge architecture multilevel inverter. This study lowers overall harmonic distortion (THD).  In this study, a novel idea for switching frequency with fewer switches is put forth. Compared to previous multilevel inverters, this idea aids in reducing the complexity of switching. A straightforward linear load is used to verify a proposed multilevel inverter with fifteen levels of output. Simulation has been used to validate the suggested concept.
