EPC develops 6 kW gallium nitride converter for 800 V DC

EPC introduced a gallium nitride-based power converter designed for 800 VDC distribution systems in AI data centers. The 6 kW converter transforms 800 V to 12.5 V using an Input Series Output Parallel topology.

AI data centers require megawatt-scale rack power delivery systems. The GaN-based converter occupies under 5,000 square millimeters with a height of 8 mm, addressing space constraints on AI boards. The converter operates close to the load, reducing bussing losses and improving system-level efficiency during the conversion from 800 VDC to 12.5 VDC.

The architecture moves from AC directly to 800 VDC at the rack level before stepping down to 12.5 V at the board. This approach eliminates intermediate conversion stages in data center power distribution. EPC is collaborating with NVIDIA on board-level conversion development for power delivery at the gigawatt scale.

EPC manufactures enhancement-mode gallium nitride-based power management products. The company’s eGaN FETs and integrated circuits are used in DC-DC converters, remote sensing technology, motor drives for electric mobility applications, robotics, drones, and satellite systems.
