Wolfspeed and LITEON just qualified silicon carbide technology for 800 VDC power systems designed to run AI data centers at scale. The partnership validates a fundamental shift in how the industry will deliver power to compute-hungry GPUs that never sleep.
Traditional data centers burn energy in conversion. Power comes from the grid as AC, gets transformed multiple times before it reaches the chip doing actual computation, and each step bleeds heat into the room. An 800 VDC architecture cuts those conversion stages dramatically, which means less waste, cooler equipment, and lower operating costs. NVIDIA launched this 800 VDC approach at Computex 2025 and the signal landed across the ecosystem immediately. This wasn't a lab experiment anymore.
LITEON showed what this looks like in practice at NVIDIA's GTC event in March 2026, running 110 kW power shelves with liquid cooling built around NVIDIA's framework. Now Wolfspeed's silicon carbide chips are part of that stack. Silicon carbide handles higher voltages and temperatures than traditional silicon without breaking a sweat, which is exactly what power-dense AI infrastructure demands.
Wolfspeed has been pushing its solid-state transformers specifically for AI applications. These compact modules replace bulky conventional transformers and let operators pack more GPU density into the same footprint. The company, formerly known as Cree, has been wrestling with the capital intensity of scaling silicon carbide manufacturing, so partnerships like this one come at a critical moment. Commercial validation matters when you need to prove your chips have high-value use cases beyond electric vehicles.
NVIDIA's active ecosystem development around 800 VDC, with multiple manufacturers now qualifying components, signals that this isn't a niche specification anymore. It's becoming the baseline for next-generation data center power delivery.
