Overview of the Interport 360 Flex System

DG Matrix has officially unveiled the Interport 360 Flex, a groundbreaking skid-mounted power system designed to revolutionize power distribution within modern AI data centers. Introduced at the OCP Global Summit between October 12 and 15, 2026, this modular solid-state transformer (SST) system efficiently converts medium- or low-voltage AC supplies into 800 VDC. The system directly addresses the escalating and highly dynamic power demands of next-generation AI infrastructure by providing a highly efficient, scalable, and flexible power conversion solution that bridges the gap between traditional grid supplies and advanced computing hardware.

Technical Architecture and Silicon Carbide Integration

At the core of the Interport 360 Flex is the Interport SST Cell, a galvanically isolated, multi-port power-conversion module. This advanced hardware leverages cutting-edge silicon-carbide (SiC) semiconductors, which are renowned for their superior switching characteristics and reduced energy losses compared to traditional silicon. To manage the intense thermal loads generated during high-power operations, the module incorporates a liquid cooling system. The system supports AC inputs up to 34.5 kV, making it highly versatile for various medium-voltage grid connections. A critical advantage of this modular design is its inherent scalability; multiple cells can be connected in parallel to form outdoor skids, allowing data center operators to seamlessly expand power capacity as their computational requirements grow without overhauling the entire system.

Interport OS and Sub-Millisecond Control Dynamics

Powering the physical hardware is the proprietary Interport OS software, which orchestrates complex power routing across cells, ports, energy storage, and sources on sub-millisecond timescales. This ultra-fast control mechanism is vital for maintaining absolute stability in high-density computing environments where microsecond-level power drops can disrupt AI training runs. The software's comprehensive feature set includes:

  • Uninterruptible power supply (UPS) operation
  • Voltage and frequency ride-through capabilities
  • STATCOM grid support and programmable protection
  • Microgrid control and AC/DC load optimization

By integrating these advanced grid-forming and grid-supporting functions, DG Matrix ensures that the power infrastructure can dynamically respond to both grid anomalies and internal facility fluctuations.

Energy Storage and AI Workload Smoothing

A standout feature of the Interport 360 Flex is its seamless integration of energy storage, specifically engineered to smooth the rapid, extreme fluctuations in power demand that are highly characteristic of AI workloads. When large AI models process data, power draw can spike instantaneously. DG Matrix has rigorously validated this smoothing capability through a year-long collaborative program with NVIDIA, focused on testing energy storage specifically for AI workload power demand smoothing. The successful completion of this extensive testing program underscores the system's operational readiness for real-world deployment in the most demanding AI environments.

Implications for Next-Generation AI Data Centers

The introduction of the Interport 360 Flex aligns perfectly with the industry's strategic shift toward 800 VDC architectures, particularly those optimized for the NVIDIA MGX framework. Transitioning to DC distribution reduces the number of power conversion stages, thereby minimizing cumulative energy losses. Crucially, the Interport system allows operators to introduce this advanced DC distribution while retaining their existing AC supplies and site infrastructure. This hybrid approach significantly reduces the friction and capital expenditure typically associated with facility upgrades, enabling data centers to scale their AI capabilities rapidly and cost-effectively.

Market Context and Future Outlook

Showcased prominently on the NVIDIA MGX Ecosystem wall at the OCP Global Summit, the Interport SST Cell highlights the growing and necessary synergy between power electronics and AI hardware manufacturers. As AI models continue to grow in complexity and scale, the need for ultra-efficient, high-density power delivery becomes an absolute paramount concern. DG Matrix’s 800 VDC SST system represents a critical step forward in this technological evolution, offering a robust, modular, and intelligent power distribution framework. Looking ahead, the widespread adoption of such solid-state transformer technologies will be essential in supporting the exponential growth of global AI infrastructure, ensuring that power delivery remains as advanced and resilient as the compute hardware it supports.
