Abstract:

This paper proposes a space vector vector pulse width modulation (SVPWM) stratey for Modular Multilevel Converters (MMCs). The proposed modulation generates multilevel output line-to-line voltages with 4N+1 levels. Furthermore, the virtual vectors are developed for the MMC and it allowed to establish the converter voltage limits and implement a proper inner currents control. Moreover, the voltages across the submodule dc capacitors can be well balanced with closed-loop controllers and a sorting algorithm. Finally, simulation results are presented to support the theoretical analysis demonstrating the good performance of the proposed modulation technique.
