英伟达与英飞凌将共同为AI数据中心电源芯片建立新架构Nvidia and Infineon to establish new architecture for power chips in AI datacentres
➀ 英伟达与英飞凌合作开发800V高压直流（HVDC）集中式电源架构，旨在取代传统分散式交流/直流系统以减少能源转换损耗；
➁ 新架构减少电源转换层级，提升效率并支持更高功率密度（预计2030年单机柜超1MW），可满足10万+ GPU集群的AI算力需求；
➂ 集中式HVDC系统增强了可扩展性、可靠性和可持续性，同时为下一代AI基础设施提供了性能保障。
➀ Nvidia and Infineon collaborate to develop a centralized 800V HVDC power architecture for AI data centers, aiming to replace decentralized AC/DC systems and reduce energy losses;
➀ The new approach minimizes power conversion stages, improves efficiency, and supports higher power densities (projected over 1MW per rack by 2030), critical for large-scale AI workloads involving 100,000+ GPUs;
➂ Centralized HVDC enhances scalability, reliability, and sustainability while meeting the performance demands of next-gen AI infrastructure.
