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
這一類無人機依靠太陽能來滿足長時間飛行的需求。太陽能系統需要最大功率點跟踪(MPPT)電路,以確保在最佳電壓下收集太陽能,然後再將其轉換為適合給備用電池充電或輸送到電力系統中間母線網路的電壓。主要目標包括:
隨著這類無人機的發展,Vicor BCM® 模組所採用的零電壓開關和零電流開關(ZVS/ZCS)等高效率電源轉換拓撲技術愈發重要,這些技術能够支持更多樣化的燃料源供給管道,滿足日益提高的功率需求。
將高壓高效地轉換為安全的48V安全超低電壓(SELV)
輕型供電網路
負載點轉換的寬輸入範圍
結合了 BCM6123 模組和 PI3741 ZVS 升降壓穩壓器,BCM6123 負責將 350V 隔離轉換為 48V 中間母線電壓,而具備超寬輸入電壓工作能力的 PI3741 則提供穩定精確的 28V 輸出,用於驅動無人機的各類負載。
