Electric vehicles are essential for the evolution of clean and green transportation. The crucial parts of vehicles that require energy are propulsion systems and charging systems. Therefore, the need of the hour is to develop high-power density, higher charging voltage levels, bidirectional operation to provide grid stability, higher operating frequency, and soft switching operation. Hence, this paper presents the design of a three-phase-threefold Dual Active Bridge (DAB) converter for a level three direct current charging station. The proposed converter interfaced with the prevailing distribution network at the input side and provides a dc link between the AC-DC converter and vehicle battery. Further, it covers the detailed design procedure to select various optimum components involved in the proposed DAB converter. As a result, it offers reliable power flow under different loading conditions and the inherent soft-switching operation. Finally, the proposed DAB converter is simulated for the power ratings of 5 kW, and the simulation results verify its working principle.
