In this study, an improved dynamic response strategy with dual phase-shift (IDR-DPS) for dual-active-bridge (DAB) DC–DC converter is proposed to improve system performance and eliminate DC bias caused by power mutation. Firstly, a unique combination of independent variables about inner and outer phase shift duty ratios is calculated at a given reference power through combining the minimum current stress calculation method with DPS control, which makes DAB run efficiently. On this basis, a DC bias elimination method is proposed to eliminate DC bias current in half a switching period through modifying inner duty ratios during transient process and drive DAB to reach new steady state quickly. Finally, a DAB topology platform is built to perform experiments of proposed IDR-DPS strategy and traditional direct control, the effectiveness of the proposed strategy is verified by comparative experiments.

具有双相移控制的改进的动态响应策略，用于双有源桥式DC-DC转换器

在这项研究中，提出了一种用于双有源桥（DAB）DC-DC转换器的具有双相移（IDR-DPS）的改进的动态响应策略，以提高系统性能并消除由功率突变引起的DC偏置。首先，通过将最小电流应力计算方法与DPS控制相结合，以给定的参考功率计算关于内外相移占空比的自变量的唯一组合，从而使DAB高效运行。在此基础上，提出了一种直流偏置消除方法，该方法通过在瞬态过程中修改内部占空比来在半个开关周期内消除直流偏置电流，并驱动DAB快速达到新的稳态。最后，构建了DAB拓扑平台，以执行建议的IDR-DPS策略和传统直接控制的实验，
