Infineon Technologies AG and DG Matrix have announced a strategic collaboration to enhance power conversion efficiency for AI data centers and industrial electrification through advanced solid-state transformer (SST) technology.
As part of the partnership, DG Matrix will integrate Infineon’s latest-generation silicon carbide (SiC) devices into its Interport™ multi-port SST platform. This integration is expected to improve efficiency, power density, and reliability while strengthening DG Matrix’s semiconductor supply chain as it scales deployments globally.
Solid-state transformers represent a key shift from traditional copper- and iron-based systems, enabling significantly smaller and lighter designs—up to 14 times smaller and 40 times lighter—while offering faster deployment and enhanced control of voltage, power quality, and energy flow. These systems are increasingly critical for connecting medium-voltage grids directly to low-voltage applications such as AI data centers, EV charging infrastructure, renewable energy systems, and industrial microgrids.
From a market perspective, this collaboration highlights the growing importance of SiC in next-generation grid infrastructure. Infineon estimates the semiconductor market for SSTs could reach up to $1 billion within the next five years, driven by rising electricity demand from AI and electrification trends.
The partnership also reflects a broader industry shift toward system-level innovation, where advanced semiconductor technologies like SiC are enabling new power architectures. DG Matrix’s multi-port SST design, combined with Infineon’s SiC roadmap, positions both companies to capitalize on emerging high-voltage, high-efficiency infrastructure requirements.
Looking ahead, the two companies plan continued alignment on future SiC developments as DG Matrix expands toward higher-voltage platforms and larger-scale deployments, supporting the transition to more efficient and resilient global power systems.
