Infineon and DG Matrix Partner to Advance SiC-Based Solid-State Transformers for AI Data Center and Grid Power Efficiency

Infineon Technologies AG has entered into a partnership with DG Matrix, a global leader in solid-state transformer (SST) solutions, to improve the efficiency of power conversion required to connect AI data centers and industrial power systems to the public grid. As part of the collaboration, DG Matrix will source Infineon’s latest generation silicon carbide (SiC) devices for use in its Interport™ multi-port solid-state transformer platform. This move strengthens DG Matrix’s semiconductor supply chain while enhancing the efficiency, power density, and reliability of SST systems deployed worldwide.

“AI data centers and next-generation electrification systems demand higher efficiency, greater power density, and uncompromising reliability,” said Andreas Weisl, Executive Vice President and Chief Sales Officer Industrial & Infrastructure at Infineon. “Solid-state technology enabled by Infineon’s leading SiC power semiconductors makes this level of performance possible. We are pleased to support DG Matrix with our latest SiC technology as they build scalable, high-performance power infrastructure. Their multi-port SST architecture represents an innovative approach to power conversion.”

Solid-state transformers are advanced semiconductor-based power conversion systems designed to replace conventional copper- and iron-core transformers. They offer significantly higher efficiency, dramatically improved power density with smaller size and lighter weight, and superior scalability. Compared with traditional transformers, SSTs can be up to 14 times smaller and 40 times lighter, while enabling faster deployment. This emerging technology is critical for linking medium-voltage grid supply directly to the low-voltage requirements of applications such as AI data centers, EV charging infrastructure, renewable energy systems, and industrial microgrids—while actively managing voltage, power quality, and energy flow. Infineon estimates that the global semiconductor market for SST applications could reach $1 billion within the next five years.

“Our multi-port architecture is designed to fully leverage the performance advantages of SiC,” said Haroon Inam, CEO and Co-founder of DG Matrix. “Infineon’s latest SiC devices strengthen our supply chain and further improve the efficiency, power density, and reliability of our Interport platform. This collaboration supports our mission to deploy faster, more efficient power infrastructure for AI data centers and electrification worldwide.”

As global electricity demand rises due to electrification and digitalization—particularly from energy-intensive applications like AI data centers—modern grids must scale while maintaining stability. High-performance semiconductors are a key enabler of this transition. Next-generation, semiconductor-based power infrastructure solutions such as DG Matrix’s SST platform contribute to building smarter, more efficient, and more reliable grids. Infineon’s advanced SiC technology plays a central role in meeting the efficiency and density requirements of these applications.

Looking ahead, as DG Matrix transitions to higher-voltage platforms and larger production volumes, the two companies plan to continue working closely on future SiC device roadmaps. The integration of Infineon’s SiC technology into DG Matrix’s expanding Interport portfolio is expected to accelerate the global deployment of scalable, resilient, and efficient power infrastructure for AI data centers and industrial power applications.
