Siemens and Reinhausen Turn up the Voltage for Hungry AI Racks

Siemens and Reinhausen turn up the voltage for hungry AI racks

Siemens and fellow German engineering biz Reinhausen are developing a solid-state transformer (SST) to deliver 800-volt DC power directly to increasingly dense AI datacenter racks. As AI hardware grows hotter and hungrier, server farm operators are looking to overhaul how power moves through their data halls. One approach, favored by Nvidia and other industry heavyweights, is distribution at 800 VDC. The two electrical enterprises are therefore …

In the era of AI, data center standardization is the name of the game - here’s why

Is Global Reference Design the answer to support this standardization?

800VDC Pushes AI Power Design From Grid To Gate

Key Takeaways: AI data centers use exponentially increasing amounts of power; the challenge now is converting high-voltage AC grid power to low-voltage chips that require DC. The 800VDC architecture for AI data centers is more efficient than 48V for traditional data centers because it requires fewer power conversion stages. It also uses less copper. Solid-state transformers support the two-stage conversion architecture, with SiC and GaN offerin…

NVIDIA Moves 800-VDC Power Architecture From Concept to Production, Just Don't Turn Off AC Power Yet

NVIDIA has transitioned its 800-VDC power architecture from a forward-looking design concept into an active production roadmap. The initial MGX-compatible 800-VDC power rack is scheduled to enter production in the second half of 2026, delivering high-voltage direct current to AI compute racks while the broader data center facility continues operating on existing alternating current distribution. This hybrid deployment model allows standard AC in…

Google, Microsoft and Nvidia back 800V DC standard for AI data centers

Google, Microsoft and Nvidia are working through the Open Compute Project (OCP) to establish 800-volt direct current (800VDC) as an open standard for powering the next generation of high-density AI data centers. The three companies are collaborating with the broader OCP ecosystem on common requirements for 800VDC power distribution, including power conversion, power quality, system interfaces and safety. The move is aimed at reducing infrastruct…
