Abstract

Multi - level inverters (MLIs) have emerged as a vital component in modern power electronics, offering superior performance in medium and high-power applications such as electric vehicles, renewable energy systems, and industrial drives. By synthesizing a staircase waveform from multiple voltage levels, MLIs significantly reduce total harmonic distortion (THD), improve power quality, and lower electromagnetic interference. This review paper provides a comprehensive analysis of various Multi - level inverter topologies, diode-clamped (neutral-point clamped), flying capacitor, and cascaded H-bridge inverters. Each topology is evaluated in terms of circuit complexity, control strategies, component count, modulation techniques, and application suitability. Furthermore, recent advancements such as hybrid topologies, reduced switch configurations, and intelligent control methods using artificial intelligence and space vector modulation are also discussed. The paper concludes by highlighting key challenges and potential future research directions aimed at enhancing the efficiency, reliability, and scalability of MLI systems.
