氮化鎵(GaN)正在改變工程師設計功率轉換系統的方式。在許多應用中,與傳統矽 MOSFET 相比,GaN 能實現更高的開關頻率、更高的效率和更高的功率密度。但 GaN 究竟在哪些方面真正優於矽?又在甚麼情況下採用 GaN 才具有工程和經濟上的合理性?在 EPC GaN 問答直播(Q&A LIVE)的首期節目中,EPC 首席執行官 Alex Lidow 回答了工程師關於 GaN 與矽技術對比的問題,涵蓋電壓範圍、開關損耗、功率密度、瞬態響應、PCB 佈局、寄生電感、閘極驅動、可靠性、成本以及與碳化矽的比較。此次討論為評估 GaN 在下一代功率轉換系統中應用的工程師提供了實用指導。

The increasing adoption of 800 V power distribution in AI data centers and industrial automation is creating a new challenge for power-conversion designers: how to convert high-voltage DC efficiently into the 6 V, 12 V and 48 Vrails required by modern loads while maintaining high power density.
A presentation by Michael de Rooij of Efficient Power Conversion (EPC) examines how a multi-stage Input Series, Output Parallel (ISOP) architecture can distribute the high-voltage input across several conversion modules, enabling low-voltage GaN FETs to be used on both the primary and secondary sides of multi-kilowatt isolated converters.

At PCIM Asia 2026, EPC presented its Gen 8 monolithic GaN power stage for AI processor power delivery.
Developed by EPC for high-frequency multiphase POL / IVR applications on next-generation AI processors, Gen 8 integrates half-bridge power switches, high-speed gate drivers, bootstrap circuitry, level shifting, and logic on the same GaN die. With lower charge, faster switching, and stronger overvoltage capability, it targets operation from a 6 V input at frequencies approaching the 10 MHz class. The system-level significance is not simply a lower component count: integration reduces drive-loop parasitics and noise sensitivity, while allowing the control side to use high-speed processes better suited to extensive digital functionality, enabling more phases and denser processor-side placement.

隨著人工智慧(AI)工作負載的快速成長,現代資料中心的電力需求正發生巨大變化。隨著NVIDIA Vera Rubin等GPU平台推動機櫃功率從200 kW邁向1 MW,傳統的48 V匯流排配電方式由於龐大的導通損耗,在實際建置和經濟效益方面均變得不切實際。在電流到達伺服器電路板之前,48 V匯流排中的電流就可能超過4,000 A。

GaN FET 與任何其他類型的電晶體一樣,在開關過程中會耗散 功率 ,並以熱量的形式表現出來。如果超過特定的溫度限制,可能會損壞這些元件。因此,熱管理是轉換器設計中的重要環節。
