Navitas introduced a production-ready 12-kW PSU reference design that achieves 97.8% effectivity for hyperscale AI information facilities with 120-kW rack densities. The design incorporates three-phase interleaved TP-PFC and FB-LLC phases, applied utilizing Gen-3 Quick SiC MOSFETs and 4th-generation high-power GaNSafe ICs, respectively. The GaNSafe ICs combine management, drive, sensing, and important safety capabilities, whereas IntelliWeave digital management enhances total efficiency.
IntelliWeave makes use of a hybrid technique combining Vital Conduction Mode (CrCM) and Steady Conduction Mode (CCM) to optimize effectivity from mild to full load. This strategy simplifies the design, reduces part rely, and lowers energy losses by 30% in comparison with typical CCM-only options.
The PSU meets Open Rack v3 (ORv3) and Open Compute Undertaking (OCP) requirements, with dimensions of 790×73.5×40 mm. It operates from 180 VAC to 305 VAC and delivers as much as 50 VDC, supplying 12 kW above 207 VAC and 10 kW under. Options embody energetic present sharing and safety towards overcurrent, overvoltage, undervoltage, and overtemperature. It operates from –5°C to +45°C, offers ≥20 ms hold-up time at 12 kW, and limits inrush present to ≤3× steady-state present for <20 ms. Cooling is supplied by an inner fan.
