Design and Development of an Enhanced Modular Multilevel Converter Using Advanced Predictive Control for Motor Drive Systems

This paper presents the design and implementation of a Modular Multilevel Converter (MMC) integrated with a motor drive system. The MMC topology offers numerous advantages such as improved voltage waveform quality, reduced harmonics, and enhanced reliability, making it an attractive choice for high-power motor drive applications. The proposed system architecture is modular in nature, facilitating scalability and flexibility to meet varying power requirements. Design considerations including sub module configuration, control strategies, and modulation techniques are discussed in detail. Furthermore, the practical implementation aspects of the MMC with the motor drive system are presented, addressing challenges related to hardware realization, control algorithm implementation, and performance evaluation. Experimental results validate the effectiveness of the proposed system in achieving high-quality output voltage waveforms and efficient motor operation across a range of operating conditions. Overall, the presented design and implementation offer a promising solution for high-power motor drive applications, leveraging the benefits of modular multilevel converter technology.
