现在，对于汽车来说，800V架构几乎已经成了标配。更有甚者，将高压母线提高到了1000V这一等级。 之所以提高电压，是因为汽车需要更快的充电速度，同时在相同功率下，800V架构的电流相比400V架构减半。根据焦耳定律 Q=I^2Rt，电流越小，热损 耗就越小，从800V到400V热损耗能降低至原来的四分之一。所以，800V不仅更省电，还能使温度更好控制，提升了能量利用效率。 在AI数据中心领域，传统机架多为48V/54V。随着IT机架电力需求突破200kW并向MW级规模演进，空间约束与母线（busbar）可扩展性问题，使得 48V/54V供电模式的局限性日益凸显。为突破这些瓶颈，行业正加速探索高压直流（HVDC）架构。 最近，巨头们就纷纷宣布自己的计划：谷歌、微软、亚马逊、Meta等巨头开始借鉴最初为EV开发的技术，更保守地推动数据中心向+/-400VDC演进。英 伟达则更为激进，联合一众电源大厂，共同开发推进另一条对器件应力要求更高的AI电源架构路线——800V HVDC（高压直流电）架构，并准备在2027 年与NVIDIA Kyber机架系统同步量产。 可以说，在AI数据中心，也要掀起800V的革命了。 ...

如果您希望可以时常见面，欢迎标星收藏哦~ 来源：内容编译自ieee 。 在全光AI数据中心的竞争中，一家巨头如今押注了另一匹马。半导体制造巨头台积电宣布，将与 桑尼维尔初创公司Avicena合作，生产基于MicroLED的互连产品。该技术是一种务实的尝试，旨 在用光学连接取代电连接，以低成本、节能的方式满足日益增多的GPU之间通信的迫切需求。 由于大型语言模型及其同类模型的计算需求，人工智能集群在数据量、带宽、延迟和速度方面面临 着前所未有的要求。迟早，单个人工智能数据中心机架内连接处理器和内存的铜线必须被光纤取 代。"目前，人们迫切希望将光纤连接尽可能地靠近电路板，"台积电副总裁蔡崇信表示。 Avicena 提供了一种独特的方法，使用数百个通过成像型光纤连接的蓝色MicroLED来传输数据。 该公司的模块化LightBundle 平台避免了激光器及其相关的复杂性问题，这些问题会威胁其他光学 芯片的可靠性、成本和功耗。Tsai 说："这非常另类！"但它非常适合这些短距离应用，而这正是 它引人注目之处。 一条简单的光纤链路，每通道仅需 300 个像素，以 10Gb/s 的速率传输，即可延伸超过 10 米的距 离 ...
