Description
Multilevel inverters have emerged as a promising solution for improving power quality, reducing switching stress, and enhancing conversion efficiency in renewable energy and smart grid applications. Conventional two-level topologies struggle with high Total Harmonic Distortion (THD), electromagnetic interference, and bulky filters, limiting their suitability for high-power systems. To address these challenges, advanced multilevel architectures have been designed to deliver multiple voltage steps, thereby approximating a sinusoidal waveform with greater precision. This paper investigates a high-performance multilevel inverter with an optimized 15-level configuration that achieves superior harmonic reduction, enhanced voltage boosting, and reduced switching device count compared to conventional alternatives. A detailed switching sequence and operational modes are provided to demonstrate the generation of fifteen distinct output voltage levels. Simulation and analytical results validate the performance in terms of THD minimization, voltage stress reduction, and waveform quality. The proposed configuration is suitable for integration with photovoltaic systems, wind generation, and smart grid applications where reliability, efficiency, and grid compliance are essential. Furthermore, the design demonstrates modularity, scalability, and compatibility with wide bandgap semiconductors, reinforcing its role as a practical solution for modern energy systems. 2025 IEEE.
