Optimized Control of the Modular Multilevel Converter Based on Space Vector Modulation
IEEE Transactions on Power Electronics, 2018 This paper presents a general space vector modulation (SVM) method for the modular multilevel converter (MMC). Compared with earlier modulation methods, the proposed SVM method not only utilizes the maximum level number (i.e., $2n+ 1$, where $n$ is the ...
