Enphase Energy Successfully Demonstrates IQ Solid-State Transformer Technology Converting 13.8 kV AC to 800 VDC
Enphase Energy demonstrated its IQ Solid-State Transformer converting 13.8 kV AC directly to 800 VDC at its Austin, Texas R&D lab, using 132 power modules (44 in series per phase) that held stable output through load steps simulating AI compute racks. The technology eliminates multiple power-conversion stages in conventional data center architectures, reducing losses and making more power available for AI compute; each 5.5 kW module uses GaN switching, Enphase's fifth-generation Kestrel ASIC, and an in-house high-frequency transformer. Enphase plans a 34.5 kV demonstration in the coming weeks, full-system racks at megawatt scale rated power before end of 2026, and customer pilots in 2027.
