Abstract

2019 IEEE. This paper presents the design of an on-board electric vehicle charger which has the capability to transfer power in both directions, that can be referred to as V2X, where X can be replaced with home (V2H) or the grid (V2G). In the proposed topology, a dual active bridge (DAB) converter is considered to regulate the charging and discharging operations of the electric vehicle battery (EVB). The topology is fully implemented using silicon carbide (SiC) switching devices. A high-frequency magnetic-link (HFML) made with amorphous alloy core is used in the DAB converter as the power transfer component, which inherently ensures the galvanic isolation for the charger. This paper also presents a novel control scheme for the proposed EV charger that will limit the overshoot of the high frequency transformer leakage current. A laboratory scaled prototype with a field-programmable gate array (FPGA)-based control has been developed and presented as a fully on-board EV battery charging system.
