The Shift to 800V HVDC in AI Data Centers

The explosive growth of artificial intelligence computing is pushing single-rack power consumption into the multi-megawatt range. To address this unprecedented demand, NVIDIA-led 800V high-voltage direct current (HVDC) architectures are rapidly replacing traditional 48V low-voltage systems. This paradigm shift significantly reduces electrical current, minimizing copper transmission losses, shrinking cable footprints, and enhancing overall data center energy efficiency.

Synergy of SiC and GaN in Power Delivery

In the modernized power delivery chain, silicon carbide (SiC) and gallium nitride (GaN) play highly complementary roles. SiC devices act as the primary energy backbone, efficiently converting utility grid power to 800V HVDC and delivering it directly into the server room. Conversely, GaN handles the high-frequency, final step-down power delivery at the GPU level. This strategic synergy overcomes the thermal and efficiency bottlenecks that traditional silicon-based devices can no longer sustain.
