8.5kW AI data centre power supply powered by GaN and SiC
Summary
The AI-optimised 54V output PSU complies with Open Compute Project (OCP) and Open Rack v3 (ORv3) specifications and utilises high-power GaNSafe and Gen-3 Fast SiC MOSFETs configured in 3-phase interleaved PFC and LLC topologies, to ensure the highest efficiency and performance, with lowest component count. Navitas’ 4th generation integrates control, drive, sensing, and critical protection features that enable unprecedented reliability and robustness. All these features are controlled with 4-pins, allowing the package to be treated like a discrete GaN FET, requiring no VCC pin. The 3-Phase interleaved CCM TP-PFC is powered by Gen-3 Fast SiC MOSFETs with ‘trench-assisted planar’ technology, which has been enabled by over 20 years of SiC innovation and offers leading performance over temperature, delivering cool-running, fast-switching, and superior robustness to support faster charging EVs and up to 3x more powerful AI data centres. “As many as 95% of the world’s data centres cannot support the power demands of servers running NVIDIA’s latest Blackwell GPUs, highlighting a readiness gap in the ecosystem.
