摘要
针对对称双半桥双向DC/DC变换器在燃料电池电动汽车中的应用问题,通过状态空间平均法得出其动态小信号模型,构建了双闭环系统控制结构,并推导了其传递函数。在此基础上进行了电流内环和电压外环的设计和校正,通过仿真和实验验证了理论分析和设计的有效性。
The dynamic small signal model of symmetrical dual half bridge bidirectional DC-DC converter is derived utilizing the state-space averaged method, aiming at its application problem in the fuel cell electric vehicles, and the dual closeloop system control diagram as well as the associated transfer function are also proposed.Based on these works, design and correction of current inner loop and voltage outer loop are implemented, and the analysis and design validation are verified through the simulation and experiment.
