摘　　要：三端口双向DC/DC变换器的建模方法主要对谐振槽为单一电感或每个端口建模进行研究,缺少对谐振槽为LC谐振的拓扑建模。本文采用一种广义状态空间平均法对串联谐振三端口DC/DC变换器进行建模,并对系统的工作模式、动态建模过程和控制策略进行了研究。通过在MATLAB/Simulink中搭建仿真模型,对不同工作模式下功率流动进行仿真验证。结果表明,该建模方法设计的控制策略能够获得良好的系统动态响应特性。The modeling method of the three-port bidirectional DC/DC converter is mainly for the circuit structure in which the resonant tank is a single inductor,and the topology modeling of the resonant tank for the LC resonance is in lack.This paper uses a generalized state space averaging method to model the series resonant three-port DC/DC converter,and studies the system s working mode,dynamic modeling process and control strategy.By building the simulation model in MATLAB/Simulink,the power flow in different working modes is simulated and verified.The results show that the control strategy designed by the modeling method can achieve good system dynamic response characteristics.
