摘　　要：针对串联谐振型双有源桥(dual active bridges,简称DAB)双向直流变换器,该文提出一种基于变频控制的电流峰值优化控制策略.首先,利用时域分析法获得双有源桥变换器中峰值电感电流和传输功率的归一化解析式;然后,将所构建时域模型与传统基波分析法的计算结果进行比较,并推导出软开关范围且对死区时间进行分析.最后,通过仿真实验验证了时域分析结果和电流峰值优化策略.仿真结果表明,在不同功率等级下所提优化控制策略相对于现有定频控制能有效地降低电流峰值.Aiming at the series resonant type dual active bridges(DAB)bi directional DC/DC converter,the paper presents a current peak optimization control scheme based on the variable frequency phase shift control,The normalized values of peak inductor current and transmitted power in the dual active bridge converter are firstly obtained by using time domain analysis,then the established model was compared with the calculation results of the conventional fundamental analysis method.In addition,the soft switching range is derived and the dead time is analyzed.Finally,the results of the time domain analysis and the variable-frequency phase shifting optimization method are verified by simulation.The simulation results show that the proposed optimized control method can effectively reduce the current peaks under different power levels compared with existing fixed-frequency control.
