空间受限：以搭载 NVIDIA GB200 NVL72 或 GB300 NVL72 的设备为例，需配备多达 8 个电源架为 MGX 计算及交换机架供电。若沿用 54V 直流配电， 在兆瓦级功率需求下，Kyber 电源架将占用高达 64U 的机架空间，导致计算设备无安装空间。而在 2025 年 GTC 大会上，NVIDIA 展示的 800V 边车方 案，可在单个 Kyber 机架内为 576 个 Rubin Ultra GPU 供电；另一种替代方案则是为每个计算机架配置专用电源架。 随着ChatGPT、Claude以及DeepSeek等人工智能应用席卷全球，全球各大超大规模AI数据中心的电力需求可谓愈发庞大。随着人工智能工作负载的指数级 增长，正将数据中心推向电力需求的临界点。 全球AI数据中心的功耗正在从传统的每机架 20-30 kW快速跳升至500 kW甚至1 MW级别。英伟达单 AI GPU 服务器功率逼近 1kW，满配 NVL AI 服务器机 柜功率轻松突破 100kW，而规划中的 2027 年量产 1MW AI Factory 机架集群，更是对供电系统提出了颠覆性要求。 随着高性能计算算力密度的不断攀 ...

Core Viewpoint - The article highlights the rising prominence of Gallium Nitride (GaN) technology in various sectors, particularly in data centers and automotive applications, while Silicon Carbide (SiC) faces challenges. The power GaN market is projected to grow significantly, with a forecasted compound annual growth rate (CAGR) of 41% from 2023 to 2029, reaching over $2 billion [1]. Group 1: GaN Market Dynamics - NVIDIA is leading the transition to 800 V HVDC data center power infrastructure, which will significantly utilize GaN technology [1]. - Yole Group predicts that the power GaN market will grow tenfold from 2023 to 2029, driven by its higher switching frequency and power density, as well as reduced energy loss [1]. Group 2: TSMC's Shift in GaN Production - TSMC announced it will cease GaN foundry production by July 2027, citing low profit margins and a shift in focus towards advanced logic processes [6]. - This decision has forced existing customers to seek new partnerships, indicating a significant shift in the GaN foundry landscape [6]. Group 3: GaN Production Challenges and Opportunities - InnoScience, a leading domestic GaN manufacturer, emphasizes the importance of 8-inch wafer production for cost-effectiveness and scalability, arguing that 6-inch production is not viable for large-scale applications [7]. - The transition to 12-inch GaN production is seen as feasible but requires significant preparation and experience from 8-inch production [10][12]. Group 4: GaN Applications Beyond Consumer Electronics - GaN technology is not limited to consumer electronics; it has potential applications in electric vehicles (EVs) and data centers, with partnerships like that with CATL showcasing its capabilities [15][17]. - The article discusses the potential for GaN in smart and electric vehicles, highlighting its role in energy management and as part of distributed energy systems [16]. Group 5: Strategic Collaborations - InnoScience's collaboration with STMicroelectronics aims to enhance GaN power solutions across various sectors, leveraging each company's strengths to improve supply chain resilience [18]. - The partnership is expected to expand GaN product offerings and market capabilities, indicating a strategic move to solidify positions in the growing GaN market [18].
