Implementation of a 5 level modular multivel converter

Abstract

This Master 2 project explores the design and implementation of a modular multilevel converter (MMC),focusing on both theoretical and practical aspects. The theoretical component delves into the fundamentals of multilevel converters, detailing various modulation techniques employed to enhance performance and efficiency. Specifically, it examines the advantages and challenges of using these techniques in multilevel converters. The practical segment involves the simulation of a 5-level inverter using MATLAB Simulink, aimed at evaluating its performance under different conditions. Key meth- ods include the application of advanced pulse width modulation (PWM) techniques to minimize harmonic distortion and improve voltage output quality. The simulation results demonstrate a significant reduction in total harmonic distortion (THD) and efficient power conversion. Following the simulation, the project transitions to the real-world implementation of the 5-level inverter with actual components. This phase involves constructing the inverter, integrating control strategies, and testing the system’s performance. The findings reveal that the implemented inverter closely aligns with the simulated results, confirming the viability of the design for practical applications.
