Title
(EN) POWER SUPPLY AND DISTRIBUTION SYSTEM FOR DATA CENTER
(FR) SYSTÈME DE DISTRIBUTION ET D'ALIMENTATION ÉLECTRIQUE POUR CENTRE DE DONNÉES
(ZH) 数据中心供配电系统
Abstract
(EN) Provided is a power supply and distribution system for a data center. The system comprises a feed circuit, a voltage energy router and an alternating-current/direct-current load power distribution segment bus, wherein the feed circuit is connected to the voltage energy router, so as to provide an initial voltage to the voltage energy router; and the voltage energy router is connected to the alternating-current/direct-current load power distribution segment bus, so as to convert the initial voltage into a required voltage suitable for a load connected to the alternating-current/direct-current load power distribution segment bus. By means of the power supply and distribution system for a data center provided in the embodiments of the present application, buck conversion is directly performed on the initial voltage of a mains power supply by using the voltage energy router, so as to generate a required voltage suitable for a load connected to the alternating-current/direct-current load power distribution segment bus. Compared with an existing power supply and distribution system for a data center, the multi-stage conversion of a high-low voltage power distribution part and a communication power source system is reduced, thereby improving the overall efficiency of voltage conversion.
(FR) La présente invention concerne un système de distribution et d’alimentation électrique pour un centre de données. Le système comprend un circuit d'acheminement, un routeur d'énergie de tension et un bus de segment de distribution de puissance de charge à courant alternatif/courant continu, le circuit d'acheminement étant connecté au routeur d'énergie de tension, de manière à fournir une tension initiale au routeur d'énergie de tension ; et le routeur d'énergie de tension est connecté au bus de segment de distribution de puissance de charge à courant alternatif/courant continu, de manière à convertir la tension initiale en une tension requise appropriée pour une charge connectée au bus de segment de distribution de puissance de charge à courant alternatif/courant continu. À l'aide du système de distribution et d'alimentation électrique pour un centre de données selon les modes de réalisation de la présente invention, une conversion d'abaissement de tension est directement effectuée sur la tension initiale d'une alimentation électrique de secteur à l'aide du routeur d'énergie de tension, de manière à générer une tension requise appropriée pour une charge connectée au bus de segment de distribution de puissance de charge à courant alternatif/courant continu. Par rapport à un système de distribution et d'alimentation électrique existant pour un centre de données, la conversion à étages multiples d'une partie de distribution de puissance à tension élevée-faible et d'un système de source d'alimentation de communication est réduite, ce qui permet d'améliorer l'efficacité globale de la conversion de tension.
(ZH) 本申请实施例提供一种数据中心供配电系统,包括馈电电路、电压能量路由器和交直流负载配电分段母线,其中:所述馈电电路与所述电压能量路由器连接,用于向所述电压能量路由器提供初始电压;所述电压能量路由器与所述交直流负载配电分段母线连接,用于将所述初始电压转换成适用于交直流负载配电分段母线上连接的负载的所需电压。本申请实施例提供的数据中心供配电系统,采用电压能量路由器直接对市电的初始电压进行降压变换,生成适用于交直流负载配电分段母线上连接的负载的所需电压,相较于目前的数据中心供配电系统,减少高低压配电部分和通信电源系统两部分的多级变换,提高电压变换的综合效率。
