摘　　要：采用变频加三移相(TPS)的四自由度调制可以提高双有源桥(DAB)变换器工作效率。为改善四自由度调制下DAB变换器动态响应性能,提出了一种基于虚拟功率控制的自抗扰控制(ADRC)策略,建立了从虚拟功率到系统输出电压的数学模型,设计了一种四自由度调制下DAB变换器ADRC结构,并搭建了实验样机进行验证。The four-degree of freedom modulation with frequency adjustment and three-phase shift(TPS)can enhance the working efficiency of the dual active bridge(DAB)converter.In order to improve the dynamic response performance of DAB converter under four-degree of freedom modulation,an active disturbance rejection control(ADRC)strategy based on virtual power control is proposed,the mathematical model from the virtual power to the output voltage of the system is established,and a structure of ADRC under four-degree of freedom modulation is designed,a experimental prototype is built to verify the system.
