Powering AI processors – 48V vertical power delivery changes the game
AI models demand huge current, driving legacy multiphase designs past 50 phases—causing space, thermal, and control limits Vicor addresses
Off-line Front End
Vicor的系列離線前端可將任何300 Vin DC-DC轉換器，或可配置產品連接至100、115、230或240 Vac單相208 Vac三相電源。 另外，前端可提供FCC/VDE（Class B單相、Class A三相）的傳導EMI/RFI濾波、暫態突波保護、主動湧流、BUS OK狀態輸出（適用於通過其門極輸入接腳控制Vicor DC-DC轉換器模組），以及針對AC線路故障事件系統的AC OK狀態。
