Solid-state transformer specialist DG Matrix will collaborate with AI infrastructure power systems provider Skeleton Technologies to integrate Skeleton’s high-power, fast-response energy storage systems across DG Matrix’s galvanically isolated Interport multi-port solid-state transformer (SST) platform.
The collaboration spans the Interport CM medium-voltage SST skid, which converts 12–34.5 kV AC directly to high-voltage DC; the Interport CL sidecar solution, which mitigates GPU pulse loads directly in the white space; and Interport Flex, an outdoor, grey-space product that can be skid-mounted and paralleled into the Interport 360 end-to-end solution. Together, the technologies address one of the defining challenges in modern AI data centers: the extreme, repetitive pulse loads generated by GPU clusters that exceed the dynamic response capabilities of the power grid as well as conventional Uninterruptible Power Supply and battery systems.
Skeleton’s power systems are engineered to respond in microseconds to minutes, absorbing peak loads before they propagate to upstream infrastructure, while DG Matrix’s Interport routes power in real time across AC and DC sources, loads, and storage at multiple voltage levels.
As GPU cluster densities grow and power demands become increasingly dynamic, static power architectures can no longer keep pace. DG Matrix’s Interport platform already addresses this through software-defined, multi-port power routing and single-stage conversion. Pairing Interport with Skeleton’s fast-response storage closes the remaining gap, enabling the joint platform to absorb load transients, support fault ride-through, and deliver backup power with the speed and cycle life that AI workloads demand.
“The shift to 800 VDC power architecture represents one of the most important evolutions in the data centre industry” said Taavi Madiberk, CEO and co-founder of Skeleton Technologies. “As power demands for AI workloads become even greater, fast-acting energy storage is essential to ensuring that GPU bursts don’t destabilise electric grids. Working with DG Matrix gives us the opportunity to demonstrate how our high-power energy storage technologies complement solid-state transformer architectures and support more resilient, efficient data centre infrastructure.”
Recent research from SemiAnalysis projects that approximately 39 gigawatts of incremental AI data centre capacity will be served by 800 VDC architecture by 2030, with a solid-state transformer total addressable market of approximately $13 billion. DG Matrix’s Interport platform natively supports 800 VDC today, and Skeleton’s GrapheneCBU800 and GrapheneBBU800 systems are built for the same voltage class, positioning both companies at the centre of that transition.
“DG Matrix is building the power fabric for the intelligence age” added Haroon Inam, CEO and co-founder of DG Matrix. “By integrating Skeleton Technologies’ fast-response energy storage with our Interport solid-state transformer platform, we can advance a more complete architecture for AI data centers: one designed for dynamic pulse loads, resilient power, and faster deployment.”
