power supply system

Abstract

Embodiments of the invention generally relate to power supply systems. Specifically, a power supply system for an information processing system electrically coupled to an AC power source and including at least one computer unit is disclosed. The power supply system includes: at least one AC power supply unit electrically coupled to the at least one computer unit and the AC power supply; at least one DC power supply unit electrically coupled to the at least one computer unit; and a backup power supply unit electrically coupled to the at least one computer unit The at least one DC power supply unit. In response to the at least one AC power supply unit being unpowered, the at least one DC power supply unit supplies power to the at least one computer unit. A data center having the power supply system is also disclosed.

Description

technical field [0001] The present invention generally relates to the field of data processing systems, in particular to a power supply for a data processing system. Background technique [0002] Due to the rapid development of cloud computing, storing large amounts of data in data centers has become one of the mainstream trends. Data centers are large, centralized computing devices that are relatively expensive to build and typically include a large number of computer systems placed in racks. Usually, the data center is powered by a power supply system that converts the voltage of the public power supply to the voltage required by the data center. [0003] figure 1 A configuration of a known data center 100 is described, which may be a space that houses a data processing system 102 including one or more computer units 104, such as one or more servers. The one or more computer units 104 are respectively electrically coupled to a first AC power supply unit (AC PSU, AC Powe...

AI Technical Summary

Problems solved by technology

Usually, the AC power supply units 116, 120 will use an inverter (Inverter) (not shown in the figure), the use of the inverter will cause the energy efficiency of the AC power supply unit 116, 120 to decrease, so in figure 1 In the design of the power supply, the inventor needs to increase the power capacity of the backup power supply 112 (Power Capacity)

In other words, a large number of inverters of the AC power supply units 116, 120 lead to the use of the backup power supply 112 with a higher power capacity, which not only causes a substantial increase in implementation costs, but also causes a decline in energy efficiency.
