Siemens and Reinhausen turn up the voltage for hungry AI racks
Not a German cop show, but a pair of engineering firms aiming to feed 800 VDC to next-gen kit
Siemens and Reinhausen engineering companies are collaborating on a solid-state transformer (SST) to deliver 800-volt DC power directly to AI datacenter racks. This development comes as AI hardware becomes increasingly powerful and generates more heat. Server farm operators are seeking to overhaul their power distribution methods, with 800 VDC distribution favored by industry leaders such as Nvidia.
The German firms are creating a modular SST that converts medium-voltage AC into stable 800 VDC output for downstream distribution. Siemens highlights the SST's compact size and galvanic isolation, reducing conversion stages and improving efficiency for high-density AI infrastructure. Reinhausen's managing director emphasizes the importance of the technology for AI datacenters to operate efficiently and reliably.
Siemens' CEO of Electrification and Automation underscores the collaboration's role in strengthening their position in datacenter electrification. Nvidia has already developed an 800 VDC power rack for IT racks drawing 1 MW or more, and other companies like Infineon are supporting the shift to 800 VDC infrastructure.
