The principles of operation, switching strategy, and transmission power characteristics of the proposed converter under normal operation are discussed, comprehensively. Moreover, the RMS current of two transformers with different values of inductances of the inductors that are in series with the transformers; is discussed. The operation of the proposed dual active bridge (DAB) converter under the open-circuit failure of transformers is studied. In addition, the loss distribution of the proposed converter in different powers is investigated. The proposed dual-transformer-based dual-active bridge converter is compared with the presented converters. Finally, the proposed converter with a low-voltage side (<i>V_L</i>= 300 V), the switching frequency of power MOSFETs (<i>f_s</i>= 50 kHz), and an accurate model of the electric battery at a high-voltage side (<i>V_H</i>= 450 V) are simulated to verify the way of charging and discharging the electrical battery with the proposed converter under normal and open-circuit fault of transformers.</span></span></span> Dual Active Bridge Converter, Dual-Transform-Based, Open-Circuit, Fault-Tolerant, Electric Vehicles. 1 10 http://ijeee.iust.ac.ir/browse.php?a_code=A-10-4725-1&slc_lang=en&sid=1 Milad Babalou milad.babalou94@gmail.com 1800319475328460014066 0000000255553388 No Faculty of Electrical Engineering, Shahid Beheshti University, Tehran, Iran Hossein Torkaman h_torkaman@sbu.ac.ir 1800319475328460014067 1800319475328460014067 Yes Faculty of Electrical Engineering, Shahid Beheshti University, Tehran, Iran Edris Pouresmaeil edris.pouresmaeil@aalto.fi 1800319475328460014068 1800319475328460014068 No Department of Electrical Engineering and Automation, Aalto University, Espoo, Finland Nazanin Pourmoradi nazaninpourmoradi77@gmail.com 1800319475328460014069 1800319475328460014069 No Faculty of Electrical Engineering, Shahid Beheshti University, Tehran, Iran.
