Enphase co-founder says solid-state transformer can ease data centre ‘power problems’

AI-summarised brief · reviewed before publication

Enphase co-founder Raghu Belur discusses the company's solid-state transformer technology, which can ease power problems in data centres. The technology consolidates the power conversion process, eliminating multiple conversion steps and traditional uninterruptible power supply systems. Enphase has been developing this technology for AI data centres over the past nine months, leveraging its power electronics expertise. The company's SST approach converts medium voltage to 800 volts DC in a single stage, ideal for data centres with high power density requirements. This technology can help eliminate inefficiencies in traditional power delivery chains. Enphase's entry into the SST market builds on its two decades of power electronics development in residential solar, with the company positioning its IQ9 series microinverter as a solution for hyperscalers, and each 1.25MW SST unit comprising 342 microinverters.

💡 Why It Matters

  • · Enphase's solid-state transformer technology addresses the growing power delivery issue in data centres, where power density per rack has surged significantly.
  • · By eliminating the need for traditional uninterruptible power supply systems, data centres can free up valuable rack space for compute resources.
