Renesas Electronics Corporation, a top provider of advanced semiconductor technologies, announced its support for the efficient power conversion and distribution within the 800 Volt Direct Current (DC) power architecture introduced by NVIDIA. This architecture is designed to power the next generation of AI infrastructure, enabling smarter and faster AI data centers.
As GPU-driven AI workloads increase and data center power demands rise to multi-hundred megawatt levels, there is a pressing need for power architectures that are both scalable and energy-efficient. Wide bandgap semiconductors such as GaN FET switches have become critical due to their high-speed switching, reduced energy losses, and superior thermal performance. These GaN devices facilitate the implementation of 800V DC power buses within data center racks, reducing power distribution losses and minimizing the need for bulky bus bars, while allowing reuse of 48V components through DC/DC converters.
Renesas’ GaN-based solutions deliver efficient and compact DC/DC power conversion across operating voltages from 48V to 400V, with stacking capabilities up to 800V. Using the LLC Direct Current Transformer (LLC DCX) topology, these converters achieve efficiency levels as high as 98%. For AC/DC conversion, Renesas utilizes bi-directional GaN switches to streamline rectifier designs and improve power density. Their REXFET MOSFETs, drivers, and controllers further enhance the performance of these power conversion modules. More details can be found on renesas.com/power.
“AI is transforming industries at an unprecedented pace, and the power infrastructure must evolve just as quickly to meet the explosive power demands,” said Zaher Baidas, Senior Vice President and General Manager of Power at Renesas. “Renesas is helping power the future of AI with high-density energy solutions built for scale, supported by our full portfolio of GaN FETs, MOSFETs, controllers and drivers. These innovations will deliver performance and efficiency, with the scalability required for future growth.”
Renesas has published a white paper that explores the topology of its devices supporting 800V power distribution in AI infrastructure.
