Reliability and Power Loss Investigation of Hybrid Multilevel Inverter for Symmetrical/Asymmetrical Sources with Optimized Power Conversion

Abstract

Hybrid multilevel inverters (MLIs) for symmetrical and asymmetrical sources have become a vital technology for modern power conversion systems, particularly in renewable energy and industrial applications. This paper investigates the reliability and power loss characteristics of hybrid MLIs, focusing on the combination of symmetrical and asymmetrical DC sources for enhanced power efficiency. Through analytical modeling, simulation, and prototype setup the paper highlights power losses and system reliability of proposed hybrid multilevel inverter on the basis of the design parameters. Practical solutions are also proposed for minimizing power loss and maximizing reliability, making hybrid MLIs an effective solution for sustainable and high-performance energy conversion systems.
