摘要：

在双有源桥（DAB）“第二类”双重移相（SDPS）控制的研究基础上，以回流功率最小为优化目标，分析并推导出不同负载条件下回流功率的数学模型，提出回流功率最小化的控制策略.在该策略下，“第二类”双重移相控制的电流应力比第一类的更小，不仅可以降低开关管器件的电流应力，减少磁性元件的损耗，还可以提高变换器的效率.研制小功率实验平台，开展实验验证.实验结果表明，相对于传统的单移相控制和“第一类”双重移相控制，该控制策略显著提升了变换器电流应力、磁性损耗和效率等方面的性能.
Abstract:

A reflux power optimization control strategy based on the existing research work of the second-dual-phase-shifting (SDPS) control of dual active bridge (DAB). The reflux power was optimized according to the derived mathematical model of reflux power on conditions of different loads. Current stress of the second-dual-phase-shifting control was smaller under this strategy compared with the first-dual-phase-shifting control. The strategy can not only make the requirements of switching devices lower, reduce the loss of magnetic elements, but also improve the efficiency of converter. The control method was verified in a small power experiment platform. The experimental results show that the control strategy can improve property of current stress, magnetic loss and efficiency of converter, which is better than single and the first dual-phase-shift controls.
