Abstract
Aiming at the problems of large output voltage overshoot and long adjustment time caused by port power coupling during the dynamic power regulation process of Triple Active Bridge (TAB) converter under the load switching application, this paper proposes a load-current feed-forward control method based on decoupling network, which has the advantages of faster dynamic response and higher control precision. Firstly, the power transmission characteristics between ports of TAB converter are analyzed. The power coupling characteristics between ports are analyzed by establishing the load current small signal model, and the diagonal decoupling network matrix is derived. Then the decoupling matrix is added to the load-current feed-forward control loop, and the load-current feed-forward controller based on the decoupling network is designed. The stability of the control strategy is analyzed by transfer function and Bode diagram. Finally, the simulation model of TAB converter is built in Matlab/Simulink simulation environment, and the correctness and effectiveness of the control strategy proposed in this paper are verified by simulation.
