摘　　要：在新能源日趋广泛应用的前景下,微网和电动车辆的能源系统要求能连接不同的能源,因此多端口变流器在新能源发电和电动汽车等方面的应用得到了越来越多的关注。多端口变流器可容纳不同的能源并结合它们各自的优点,尤其有利于实现能量系统内部的协调和优化控制。建立了三有源桥(TAB)变流器的平均状态空间数学模型,并在此基础上推导出小信号模型和等效电路,最后基于小信号模型对双闭环控制系统的设计和优化进行了讨论,并通过仿真和实验验证了所提出三有源桥变流器的性能。The new energy is becoming more and more extensive application prospects, it requires that energy system of micro-networks and electric vehicle can connected with different energy, so the multi-port converters in new energy power generation,electric vehicle and other applications has attracted more and more attention.Muhi-port converter can accommodate different energy and combine their respective advantages, especially conductive to the realization of the energy system of internal coordination and optimization control.Aiming at a triple active bridge（TAB） converter, the average state space mathematical model is established, and the small signal model and equivalent circuit is derived.Finally ,the design and optimization of double closed-loop control system based on the small signal model are discussed.The simulation and experimental results are presented to verify the performance of the proposed converter.
