The paper proposes a hybrid control strategy to achieve stable operation of the T-type three-level rectifier. The control method includes inner loop and outer loop, the outer loop adopts PI controller to realize DC side voltage stability and reactive power acquisition, and the inner loop adopts finite set model predictive control to realize input current control. The problem of midpoint imbalance of T type three-level rectifier is solved by adjusting the vector action time. The hybrid control method proposed in this paper has the following innovations: 1 fast dynamic response; 2 less PI parameters; 3 less calculation; 4 no need of adjusting modulation stratege. Finally, the correctness and effectiveness of the proposed method are verified by simulation and experiment. [ABSTRACT FROM AUTHOR]
