The demand of grid interaction with battery-operated systems requires the bidirectional operating capability of battery chargers. The typical charger design is based on dual stage converter with an AC/DC section for grid connection and a DC/DC section for battery charging. In this presentation, a 25kW high voltage DAB converter with optimized modulation technique for battery charging is introduced, showing the efficiency benefits of the latest generation SiC MOSFETs combined with the high performance of a dedicated microcontroller for power conversion applications.
