Abstract

Since the year 2000, the up to 400 Volt Direct Current (400VDC) powering interface for Telecom and Datacenters equipment has been standardized and industrialized as it brings advantages. Compared to 48 Volt Direct Current power solutions, it uses much less copper and the energy losses in cable are lower. Compared to Alternating Current uninterrupted power supply (UPS) benefits are simplicity higher reliability and scalability with higher modular design. Now large implementations projects in thousands of Telecom networks sites and Megawatt datacenters are operated under 400VDC and acceleration of the use of this voltage interface requires solutions to simplify the migration towards 400V DC with progressive steps on many other sites. At the same time extended use is proposed for coupling renewable energy to the local DC power station and for remote powering of Telecom access network nodes. This paper will present the issues and the status of solutions found to accelerate the adoption of the 400V DC solutions in all these cases.

电信运营商将加速向电信/ICT设备400伏直流高效供电的迁移，并将耦合站点迁移到智能能源微电网

自2000年以来，电信和数据中心设备的高达400伏直流(400VDC)供电接口已经标准化和工业化，因为它带来了优势。与48伏直流电源解决方案相比，它使用的铜少得多，电缆的能量损失也更低。与交流不间断电源(UPS)相比，其优点是简单，可靠性高，模块化设计高，可扩展性强。现在，数千个电信网络站点和兆瓦级数据中心的大型实施项目在400VDC下运行，加速使用这种电压接口需要解决方案，以简化向400V直流的迁移，并在许多其他站点上逐步进行。同时提出了可再生能源与本地直流电站耦合和电信接入网节点远程供电的扩展利用。本文将介绍在所有这些情况下加速采用400V直流解决方案的问题和解决方案的现状。
