Siemens and Reinhausen move to industrial-scale solid-state transformers for data centers
Siemens and Reinhausen said (2026-08-17) they plan to produce solid-state transformers (SST) for data-center DC power supply at industrial scale, but gave no timeline. The development ties into the 800 VDC approach to AI power supply, which connects large consumers to the medium-voltage grid.
Who is affected and how
- engineer
- The shift toward 800 VDC power architecture brings new design standards and component requirements.
- supplier
- SST and DC distribution may create new demand for circuit and cooling components.
- energy specialist
- Grid connection is decided on the medium-voltage side, so SST maturity affects the connection plan.
