چکیده :

Multilevel inverters (MLIs) represent a fundamental technology in modern power electronics, serving critical roles in energy conversion, renewable source integration, and power quality enhancement. This research presents a comprehensive comparative analysis of six major MLI topologies: Neutral Point Clamped (NPC), Flying Capacitor (FC), Cascaded H-Bridge (CHB), Modular Multilevel Converter (MMC), Packed U-Cell (PUC), and Packed E-Cell (PEC). The evaluation encompasses multiple performance criteria including cost, control complexity, efficiency, and reliability under standardized conditions. Each topology demonstrates distinct advantages and limitations across different application domains. The PUC converter exhibits reduced component count (87.5% fewer switches than CHB) and achieves 97.8% efficiency, while CHB topologies provide superior fault tolerance through modular architecture. MMC systems excel in high-voltage applications with scalability advantages, whereas conventional topologies like NPC and FC offer proven reliability in industrial applications. Recent developments in wide-bandgap semiconductors (SiC/GaN) and artificial intelligence integration present opportunities for performance optimization across all topologies. This study establishes systematic evaluation criteria and identifies future research directions, including advanced semiconductor integration and machine learning applications for predictive maintenance.
