"Data centers face a conundrum: how to power increasingly dense server racks using equipment that relies on century-old technology. Traditional transformers are bulky and hot, but a new generation of solid-state transformers promises to address both problems while making power management more flexible. One solid-state transformer startup, DG Matrix, has raised $60 million in a Series A round, TechCrunch has exclusively learned. Engine Ventures led the round with ABB, Cerberus Ventures, Chevron Technology Ventures."
"Altogether, one Interport can cut down the amount of space devoted to power conversion in a data center. Two four-by-30 foot skids laden with power conversion equipment can be replaced by a single four-by-four foot Interport device, DG Matrix co-founder and CEO Haroon Inam told TechCrunch. By eliminating several devices, the company can boost the system's overall efficiency. All the legacy devices chained together can achieve about 82% to 90% efficiency, Inam said, while Interport is 95% to 98% efficient."
DG Matrix developed the Interport solid-state transformer to consolidate and route electricity from multiple sources for data centers, handling up to 2.4 megawatts. Interport can aggregate inputs such as solar panels and grid-scale batteries to directly power high-density racks, enabling examples like combining 600 kW solar and 600 kW battery to serve twelve 100 kW racks. The device removes the need for multiple legacy power conversion components and UPS, shrinking equipment footprint from large skids to a single compact unit and raising end-to-end efficiency to roughly 95–98%. DG Matrix secured $60 million in Series A funding.
