Wolfspeed and LITEON are joining forces to develop 800 VDC power solutions purpose-built for AI data centers, with LITEON qualifying Wolfspeed’s silicon carbide technology for integration into high-efficiency power modules.
AI data centers running power-dense GPUs around the clock rely on power delivery systems where every conversion from one form to another wastes energy as heat. Traditional AC-based data center architectures involve several conversion steps between the utility grid and the chip doing the actual computation. An 800 VDC architecture dramatically reduces those conversion stages, meaning less waste, less heat, and lower operating costs.
NVIDIA launched its 800 VDC power architecture at Computex 2025, signaling to the industry that this wasn’t a theoretical exercise but rather the direction the entire ecosystem needed to move. LITEON demonstrated integrated 800 VDC solutions at NVIDIA’s GTC 2026 event, which ran from March 16 to 19, 2026. Those demonstrations included 110 kW power shelves and liquid-cooling solutions designed to work within NVIDIA’s architectural framework.
By qualifying Wolfspeed’s silicon carbide technology, LITEON is adding another performance layer to its power delivery stack. Silicon carbide, or SiC, is a wide-bandgap semiconductor material that handles high voltages and temperatures far better than traditional silicon.
Wolfspeed has been actively promoting its SiC-based solid-state transformers and power modules specifically for AI factory applications. These solid-state transformers are designed to enhance GPU density and operational efficiency by replacing bulky conventional transformers with more compact, efficient alternatives.
Wolfspeed, previously known as Cree, has been navigating the challenging economics of scaling silicon carbide manufacturing, a capital-intensive process that has pressured its balance sheet. Partnerships like this one with LITEON provide commercial validation for Wolfspeed’s technology at a time when the company needs to demonstrate that its SiC chips have clear, high-value applications beyond the electric vehicle market.
NVIDIA’s active development of an 800 VDC ecosystem, with multiple hardware partners across the supply chain, including LITEON and Wolfspeed, signals that this architecture is moving toward widespread commercial deployment. Wolfspeed and LITEON join an expanding ecosystem that includes other power semiconductor firms, underscoring a collective effort toward advancing new power architectures for next-generation AI workloads.
