An Innovative Multilevel Self-Boosting Inverter for Grid-Connected Photovoltaic System

This article, has an rising demand for electricity and the depletion of fossil fuels, Systems that userenewable energy are currently acknowledged is the primary substitute power source. One type of renewableenergy source that is expanding quickly is the photovoltaic (PV) system. PV systems are integrated with theutility grid through the use of inverters. The most popular option for solar applications is multilayer invertersbecause to their reduced total harmonic distortion (THD), switching stress, and electromagnetic interference.This work introduces a five-level grid-connected inverter at a low cost. Six unidirectional switches, onediode, and one switched capacitor are used in the suggested inverter. It also does away with the need forseveral separate independent DC sources. An appropriate switching pulse for the inverter is produced usinga straightforward modulation method. The MATLAB/Simulink simulation results are used to demonstratethe efficacy of the suggested multilevel inverter.
