The Development of Decentralized Space Vector PWM Method for Multilevel Multiphase Converters

In this paper, the decentralized modulation for the control of multilevel multiphase converters (MMC) using space vector pulse-width modulation (SVPWM) is proposed. With the proposed method, local information obtained from neighboring cells and by itself is employed so that the cell can adjust the vector and the switching time of the vector itself. In addition, decentralized control also increases operational flexibility (power and voltage adjustment) and dynamic reconfiguration of the MMC system. The simulation results show the feasibility and effectiveness of the proposed method.
