Analysis of Isolated DC-DC Coupled-Inductor Based Dual Active Bridge Converter for EV Charging Systems
The isolated DC-DC converter is capable of regulating the DC voltage by maintaining a small input ripple current, high efficiency, and high voltage transfer ratio. This work discusses a coupled-inductor based dual active bridge (CIDAB) converter for charging of electric vehicles (EVs). Interleaved coupled inductor, built-in transformer, and switched-capacitor concepts are used in this converter to provide high voltage gain, low current, and high efficiency. A current-fed coupled inductor-based DAB converter is selected for the charging of the EV battery. The various operating modes of CIDAB as well as their closed-loop analysis are demonstrated. Further, the simulation analysis is executed through MATLAB 2021a for the implementation of a closed-loop analysis of CIDAB and the charging and discharging of the EV battery. It is observed that the higher output power can be obtained in CIDAB as compared to dual active bridge (DAB).
