Abstract

Multilevel inverters play a critical role in renewable energy systems by enabling efficient power conversion and enhancing power quality. With the increasing integration of renewable energy sources, such as solar photovoltaic (PV) and wind, there is a growing need for advanced control strategies to ensure reliable operation and minimize harmonic distortion. This paper explores various control techniques for multilevel inverters, focusing on improving the quality of power delivered to the grid and reducing energy losses. The proposed strategies include the use of pulse width modulation (PWM) schemes, artificial intelligence (AI)-based controllers, and hybrid control algorithms to enhance the performance of multilevel inverters. Simulation results demonstrate that these advanced control strategies effectively improve the power quality and overall efficiency of renewable energy systems. This research provides insights into optimizing multilevel inverter design for better performance in modern renewable energy applications.
