Abstract

This paper verifies the potential of utilizing the Dual Active Bridge (DAB) converter as a 10 kW Power Electronics Building Block (PEBB) for the charging of Electric Vehicles (EVs) where a wide output voltage range is required. Following the tendency of the new EV charging standards from CCS and CHAdeMO, the commonly employed isolated DC-DC converter should be able to supply the rated power for different vehicles which employ battery technologies which could range from 300 V up to 1000 V. Rectangular (or phase-shift), triangular and trapezoidal modulation strategies are investigated, of which the last two techniques are used for designing the PEBB. Suitable SiC-based semiconductors are chosen, the passive components are designed and the power losses are derived for the whole operating range. It is found that a high power efficiency can be achieved using the designed system.
