Abstract

The embodiment of the invention provides a power supply system for a data center, relates to the field of a power system, and aims at solving the problems of small efficiency of a power supply of a server of the data center and large energy consumption of the power supply system caused by the double-power sharing mode and UPS (Uninterrupted Power Supply) of the server. According to the specific scheme, the power supply system comprises a first commercial power supply device, a second commercial power supply device and a high voltage DC system, wherein the first commercial power supply device is used for outputting first commercial power and supplying power to a server through a power supply of a first server; the second commercial power supply device is used for outputting second commercial power in case of failure of the first commercial power and supplying power to the high voltage DC system and the power supply of a second server; the high voltage DC system is used for converting the AC of the second commercial power into the high voltage DC to be output to the power supply of the second server; the power supplies of the first server and the second server both comprise voltage regulating switches for regulating output voltage of the power supply of the first server or the power supply of the second server; the power supplies of the first server and the second server are connected in parallel to supply power to the servers. The power supply system supplies power to the data center.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a power supply system for a data center. Background technique [0002] The data center is a specific equipment network for global collaboration, which plays an important role in the accelerated transmission, calculation and storage of data information. Therefore, for the power supply system of the data center, on the one hand, the power supply system is required to have high availability to ensure the reliability of the data center. On the other hand, the power supply system is required to reduce energy consumption and cost as much as possible. [0003] Most of the traditional data centers adopt a dual-server power supply mode with two equal distribution channels and realize uninterruptible power supply through an (Uninterruptible Power System, UPS) power supply system. Among them, UPS uses internal filters, voltage regulators, inverters and other devices and battery components to r...
