Press Release14 August 2026Siemens AGMunich
Siemens and Reinhausen are developing power solutions for AI data centers
AI is
driving a fundamental transformation of data center infrastructure. The
industry is moving from traditional power architectures towards more efficient
and scalable solutions capable of supporting the next generation of AI
workloads. SSTs are one of the key building blocks of that transition. They
enable higher efficiency, direct grid-to-rack DC conversion, and a reduced
footprint. By responding to load changes in milliseconds, they seamlessly
handle the extreme power swings of AI training workloads avoiding downtime
while cutting costs.
A
medium-voltage SST provides a compact and efficient alternative to conventional
multistage AC/DC power-conversion architectures, enabling a more efficient
power delivery to high-density AI infrastructures.
Reinhausen is
the world’s leading manufacturer of voltage regulation technology for power transformers and has
decades of experience in power quality and grid stability. The company has also
developed extensive know-how in the field of medium voltage power electronics
and related components, which are at the heart of modern SST architectures.
Siemens
combines deep expertise in power electronics, electrical power solutions, grid
protection and automation systems as well as digitalization. In the deployment
of SSTs, Siemens applies its capabilities in grid integration, power
conversion, protection and control to deliver the next-generation energy
systems for AI data centers.
Key features of the
offering include modularity, scalability, and high availability. The design
supports operation up to 36 kV AC and can be modularly applied to
lower voltages, making the architecture scalable for different grid-connection
conditions. The SST delivers a stable 800 VDC output typically required by
AI-enabled data centers.
