Solid-State Transformers: The Next Power Revolution for Data Centers and Beyond

Data centers are facing an unprecedented challenge: how to power increasingly dense server racks with equipment that still relies on century-old technology. Traditional transformers are bulky, generate excessive heat, and struggle to keep pace with the exponential growth of computing demands. But a new generation of solid-state transformers promises to solve both problems while making power management more flexible than ever before.

One startup at the forefront of this revolution, DG Matrix, has just secured a massive $60 million Series A funding round, according to an exclusive report by TechCrunch. The round was led by Engine Ventures, with participation from major players including ABB, Cerberus Ventures, Chevron Technology Ventures, Clean Energy Ventures, Fine Structure Ventures, Helios Climate Ventures, MCJ, and Piedmont Capital. This substantial investment signals strong confidence in the company’s vision to modernize power infrastructure across multiple industries.

The Interport Device: Power Management Reimagined

At the heart of DG Matrix’s innovation is the Interport device, a compact power router that fundamentally changes how electricity flows through data centers. According to Subhashish Bhattacharya, co-founder and CTO of DG Matrix, one Interport can handle up to 2.4 megawatts of connections. This means it could simultaneously manage power from diverse sources—say, 600 kilowatts from solar panels and another 600 kilowatts from grid-scale batteries—to supply 12 server racks drawing 100 kilowatts each.

The implications are profound. Because Interport can integrate electricity from multiple sources seamlessly, DG Matrix claims it can eliminate the need for traditional uninterruptible power supplies (UPS) and the extensive supporting infrastructure they require. This consolidation represents a paradigm shift in data center power architecture.

Space and Efficiency Gains That Matter

The physical footprint reduction is staggering. Where two four-by-30 foot skids laden with traditional power conversion equipment once stood, a single four-by-four foot Interport device can now do the job. Haroon Inam, co-founder and CEO of DG Matrix, emphasizes that this isn’t just about saving space—it’s about fundamentally improving system performance.

Traditional power conversion chains typically achieve 82% to 90% efficiency, but Interport pushes this to 95% to 98%. “When you are using only 10%, 15% of the components that legacy systems use, you’re going to be far more reliable,” Inam explains. Fewer components mean fewer points of failure, translating directly to improved uptime for mission-critical data center operations.

From Data Centers to Global Impact

Currently, data centers represent about 90% of DG Matrix’s pipeline, with the remainder focused on electric vehicle charging for fleets. However, the company’s ambitions extend far beyond these initial markets. The next frontier includes building power systems and creating micro- and mini-grids to support electrification projects in remote communities.

In these off-grid applications, Interports would orchestrate power from solar, wind, and battery storage to provide reliable, round-the-clock electricity without any connection to traditional power grids. “Nobody’s going to build a $100 million transmission line to a village,” Inam notes. “Now you can spend a fraction of that money and help eliminate energy poverty.”

Real-World Deployment and Future Products

DG Matrix is currently rolling out initial units to customers, with deployments beginning in June. The company isn’t stopping there—their next product will be a “sidecar” device specifically designed to supply power directly to data center racks, building on the core technology already proven in the Interport.

The company has also secured a significant partnership with Exowatt, the startup building solar-plus-storage containers to supply data centers with 24/7 renewable electricity. This collaboration demonstrates how solid-state transformers can integrate with renewable energy systems to create truly sustainable data center operations.

Why This Matters Now

The timing couldn’t be better. As artificial intelligence workloads explode and data centers consume ever-increasing amounts of power, the limitations of traditional transformer technology become more apparent. The combination of space constraints, efficiency requirements, and the push toward renewable energy integration creates the perfect conditions for solid-state transformer adoption.

DG Matrix’s approach addresses all these challenges simultaneously: reducing physical footprint, improving efficiency, enabling renewable integration, and cutting costs. The $60 million investment round suggests the market recognizes this technology as not just incremental improvement, but a fundamental shift in how we manage electrical power.

The implications extend beyond data centers. As industries electrify everything from transportation to industrial processes, the ability to efficiently manage and distribute power from diverse sources becomes increasingly critical. DG Matrix’s technology could play a crucial role in the global transition to cleaner, more resilient energy systems.

From powering the AI revolution to bringing electricity to remote communities, solid-state transformers represent a technological leap that could reshape our energy infrastructure for decades to come. As DG Matrix begins its commercial rollout, the industry will be watching closely to see if this promising technology can deliver on its transformative potential.
