Abstract

This study focuses on THD and various modulation strategies while analyzing 5-level and 7-level multilevel inverters for grid systems. As they enable effective DC-to-AC conversion with advantages like lower switching losses, improved output quality, and compact design, multilevel inverters are essential in renewable energy applications. These inverters, which are widely used in industrial motor drives, PV systems, and electric vehicle charging, promote sustainable energy solutions. According to simulation data, the 7-level inverter provides the best performance with the lowest THD and outperforms the 5-level in terms of THD. POD is the most successful SPWM approach for reducing THD, according to a comparison analysis. These results highlight how advanced SPWM techniques and creative inverter designs can enhance grid integration and power quality.
