VisIC offers smallest 6.7kW on-board charger reference design for EV market

VisIC Technologies Ltd of Nes Ziona, Israel – a fabless developer of power conversion devices based on gallium nitride (GaN) metal-insulator-semiconductor high-electron-mobility transistors (MISHEMTs) – has announced the availability of its on-board charger (OBC) reference design for the fast-growing electric vehicle (EV) market.

The 6.7kW OBC has a size and weight of only 2.3L and 4.5kg respectively, providing nearly 3kW/L power density (3x better than existing commercially available products). With efficiency above 96% across a wide load range, it helps automotive manufacturers to reduce power losses and enables faster charging for electric vehicle owners, says VisIC.

The 6.7kW OBC using VisIC’s GaN power devices targets plug-in hybrid vehicles/electric vehicles (PHEV/EV) applications. With a universal 110‐220V/16-32A AC input and 200‐430V DC output for charging the automotive battery by controlling voltage and current flow to the battery, the charger is designed to provide the interfaces to charging standards on the input power side and thus adapts to charging infrastructure.

The OBC design using VisIC’s GaN technology, designed for AEC-Q101 automotive qualification requirements, demonstrates a reduction in power losses, size and weight, says the firm. The overall advantages include simplifying the cooling systems, reducing the charging time, and reducing the size and cost of the electric vehicle.

“This reference design proves the benefits and improvements VisIC’s GaN technology can bring to the xEV users,” says Ran Soffer, senior VP sales & marketing. “With VisIC’s GaN technology, electrical cars will be more efficient, lighter in weight and more affordable.”

VisIC is exhibiting in booth #775 at the Applied Power Electronics Conference & Exposition (APEC 2019) in Anaheim, CA, USA (19-21 March) and in booth #4800 (Hall E4) at electronica China 2019 in Shanghai (20-21 March).
