Investigation Of Field Oriented Control Of PMSM Drive Performance Using Advanced Multilevel Converter Topology

Abstract

This study investigates the performance characteristics of a Permanent Magnet Synchronous Motor (PMSM) drive system powered by a Modular Multilevel Converter (MMC). MMCs are gaining prominence in motor drive applications due to their ability to deliver high-quality output voltage, scalability, and reduced harmonic distortion. The research focuses on analyzing both transient and steady-state behaviors of the MMC-fed PMSM system. Key indicators such as torque response, speed stability, harmonic content, and overall efficiency are evaluated under varying operating conditions. Simulation-based results highlight the advantages of using MMCs over traditional inverter configurations, particularly in enhancing output waveform quality and control accuracy. This work contributes to a deeper understanding of integrating MMCs with PMSMs for advanced drive applications, especially in high-power environments.
