A bidirectional dual active bridge converter for V2G applications based on DC microgrid

Abstract

DC microgrids are becoming more and more popular since they are considered the next generation power systems. In the meantime, Electric Vehicles (EVs) have gained increased popularity because they can be a promising solution to the rising concerns about environmental and energy issues. Due to the attractiveness of the Vehicle to Grid (V2G) technology, the present study focuses on designing a bidirectional DC charger of an EV. The DC-DC converter used in this study is the Dual Active Bridge converter. A design methodology as well as a control strategy is proposed. The proposed charging configuration has been simulated in Matlab/Simulink. Some interesting results about the effectiveness and the dynamic response of the proposed configuration have been obtained.
