Abstract
AbstractProduction of renewable energy sources (RES) has been exponential in the present years and is essentially driven by factors like the escalation of greenhouse emissions with depleting in fossil fuel reservoirs. Photovoltaic (PV) energy, a prominent RES, produces electricity directly from sunlight. Nowadays, multilevel inverter (MLI) is broadly worn in incorporation with RES and drives application. Among various RESs, PV energy is the most generous and reliable. In this manuscript reduced device count multilevel inverter (RDC MLI) incorporate with PV system with maximum power point tracking technique (MPPT) and compared with cascaded multilevel inverter (CHB MLI). Based on genetic algorithm (GA), selected harmonic elimination (SHE) technique is considered for generate the proper firing angles of PV support MLIs. The obtained firing angles are suitable to reduce the total harmonic distortion (THD) of MLIs. The PV with RDC MLI is produced less THD as compared to PV CHB MLI. Analysis of results is based on MATLAB/Simulink software platform.KeywordsReduced device count multilevel inverter (RDC MLI)Selected harmonic elimination pulse width modulation technique (SHEPWM)Total harmonic distortion (THD)Genetic algorithm (GA)
