摘要：
The control strategy of dual bridge series resonant DC/DC converter (DBSRC) system based on the input series output parallel (ISOP) connection is studied in this paper. The small-signal models and the corresponding transfer function of DBSRC and its ISOP system are constructed through the periodic averaging method, where the input voltage of one DBSRC sub-module is influenced by all phase-shift angles of other sub-modules. In order to achieve the input voltage balance of different sub-modules, a differential input voltage sharing (DIVS) control strategy is proposed. This strategy realizes the decoupling control of the output voltage regulation loop and the input voltage sharing regulation loop in the system block diagram. Compared with the traditional input voltage sharing control strategy, this strategy requires less communication data and has higher dynamic response performance. Finally, the simulation and experiments on a 12kW prototype show the correctness of DBSRC small-signal model as well as the effectiveness and superiority of DIVS control strategy. © 2020, Electrical Technology Press Co.
