Israel-based VisIC Technologies, a manufacturer of gallium nitride (GaN) power semiconductor devices for the auto, data center and industrial markets, has published a reference design aimed at the EV industry for its on-board charger (OBC) that uses its GaN technology.

The 6.7 kW OBC has a volume of 2.3 liters and weighs 4.5 kg, providing a power density of just under 3 kW/L . VisIC claims its efficiency is over 96% across a wide load range. The company plans to offer the OBC power device for both PHEV and EV applications. The OBC can handle 110‐220 V/16-32 A AC input and outputs of 200‐430 V DC.

The manufacturer says the OBC design with GaN technology can simplify EV cooling systems and reduce charging time and power losses.

VisIC Vice President Ran Soffer said, “With VisIC’s GaN technology, electric cars will be more efficient, lighter in weight and more affordable.”
