Enphase Energy says developing solid state transformer for AI data centers

Enphase said: “We announced today that Enphase is developing its 1.25 MW IQ Solid-State Transformer product for data centers, a distributed solid-state transformer platform designed to convert medium-voltage AC directly to low-voltage DC in a single stage. The IQ SST will be built as a supercluster of 342 power modules, with each module powered by Enphase’s custom Kestrel ASIC and high-frequency GaN-based power platform. The architecture is designed to deliver native 800 V DC output for next-generation AI racks, fast response on the order of 1 to 3 milliseconds, built-in redundancy, and serviceability through hot-swappable modules. Enphase has completed feasibility, built working power modules, converged on the system design, and has more than 80 engineers working on the program. Full system demonstrations are expected later this year.”
