Enphase will be at Booth 1454, showcasing its approach to next-generation AI data center power infrastructure, including the IQ® Solid-State Transformer (IQ SST). On Sept. 15 at 12:00 p.m. PDT, Raghu Belur, co-founder and chief product officer at Enphase Energy, will present “Solid-State Transformers: Speed to Power” on the AI Data Center Track. The IQ SST is being developed to convert medium-voltage AC directly to 800 VDC for high-density AI data centers, with expected sub-millisecond response to dynamic AI loads. Its distributed architecture is designed to scale to racks up to 5 MW. “AI data centers are forcing the industry to rethink how power moves from the grid to the rack,” said Raghu Belur. “At AI Infra Summit, we will show how Enphase is applying high-frequency magnetics, GaN power switching, custom silicon, and scalable domestic manufacturing to this challenge.” Enphase recently began building IQ SST power modules at its manufacturing facility in Arlington, Texas, to assemble and validate full-scale IQ SST racks.
