摘要
In this paper, one kind of two-stage bidirectional AC/DC converter for battery formation is studied. And the post-stage DC/DC converter based on the full-bridge and push-pull structure is the focus of the study. Firstly, the small signal model is built for the bidirectional DC/DC converter. And then the control compensator is designed. The control method based on one kind of bidirectional switching control strategy with a common inner ac current-loop and an external voltage-loop double-loop design is used to realize the bidirectional operation. Also, the bidirectional switching control strategy based on digital control platform is designed. At last, a prototype of the bidirectional DC/DC converter is fabricated. The experiments results verify the correctness of the control loop and the bidirectional switching control strategy.
