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 developing a modular SST capable of converting medi
