Experimental Investigation of Modular Multilevel Converter Using Space Vector Pulse Width Modulation

다국어 초록 (Multilingual Abstract)

The modular multilevel converter (MMC) is a promising topology for high-voltage and high-power applications due to its modularity, scalability, and low harmonic distortion. In this paper, the design and implementation of an MMC using space vector pulse width modulation (SVPWM) technique is presented. The SVPWM technique is used to generate the switching signals for the MMC to achieve a high-quality output voltage waveform with low harmonic distortion. The MMC is designed using half-bridge sub-modules with a DC capacitor voltage balancing control method. The performance of the proposed MMC topology is validated through simulation studies in MATLAB/Simulink and hardware implementation using fi eld programmable gate array platforms. The results show that the proposed MMC using SVPWM technique achieves a better output voltage waveform with low harmonic distortion compared to the conventional pulse width modulation (PWM) technique. The proposed MMC topology is suitable for high-voltage and high-power applications such as renewable energy systems and electric vehicles.
