摘要：
Dual active full -bridge (DAB) DC-DC converters are widely used in DC microgrids and various fields of power electronics. It has the advantages of high -power density, easy to implement soft switching and bi-directional power transfer capability. Conventional linear controllers have difficulty in meeting the increasing demands for speed and robustness. In this paper, a control strategy based on the Brayton-Moser theory of power shaping is proposed to improve the control strategy of DAB DC-DC converters. The DAB DC-DC converter is modelled and the controller is designed based on the Brayton-Moser power -shaping theory. A simulation of the DAB DC-DC converter is constructed and a comparative analysis is carried out for three control strategies of PI control, passive control and power -shaping Brayton-Moser control under different operating conditions.
