| Abstract: | In order to facilitate the stability analysis of the bidirectional full-bridge DC-DC converter and the design ofthe closed-loop controller, the bidirectional full-bridge DC-DC converter operating in the dual phase-shift control modewas modeled by the generalized state space averaging method, and a large signal model of the system was obtained. Thesmall signal model was obtained by linearizing the large signal model, and the controller design was based on the small-signal model. Finally, the accuracy of the established model and the stability of the closed-loop system were demonstratedby MATLAB simulation. The simulation results show that the small-signal model can accurately follow the system output,and the closed-loop system meets the requirements of GJB181B. |
