摘要：This paper proposes a multi-function modular multilevel conversion system for electric vehicle, which can solely provide the motor driving function, as well AC and DC battery charging functions. To well illustrate the proposed system, the operational principles and control strategies are fully investigated including state of charge (SOC) balancing control strategy in driving mode, DC or AC charging methods in charging mode. Finally, the proposed power conversion system was verified through Matlab simulations and a scaled down experimental prototype. © 2020 IEEE.
