N2 - The necessity of incorporating a dual active bridge (DAB) converter in electric vehicles (EVs) has been widely recognized in recent years. In this paper, a DAB converter based on the utilization of two transformers is presented. Also, the principles of operation, switching strategy, and transmission power characteristics of the proposed converter are discussed. Moreover, the RMS current of two transformers with different values of the inductances of the inductors that are in series with the transformers; is discussed. In addition, the loss distribution of the proposed converter across different powers is investigated. The proposed dual-transformer-based dual active bridge converter is compared with the presented converters in terms of transmission power of transformers and efficiency of the converters. Finally, the proposed converter with a low voltage side (VL = 200 V), the switching frequency of power MOSFETs (fs = 25 kHz), and an accurate model of the electric battery at a high voltage side (VH = 400 V) are simulated at 2980 W to verify the way of charging and discharging the electrical battery with the proposed converter.
