Power source supply system

Abstract

Each embodiment of the invention generally relates to a power source supply system, and particularly discloses a power source supply system of an information processing system. The information processing system is electrically coupled to an alternating-current power source and comprises at least one computer unit, the power source supply system comprises at least one alternating-current power source supply unit, at least one direct-current power source supply unit and a standby power source unit, the alternating-current power source supply units are electrically coupled to at least one computer unit and the alternating-current power source respectively, the direct-current power source supply units are electrically coupled to at least one computer unit, the standby power source unit is electrically coupled to the direct-current power source supply units, and responding to the circumstance that the alternating-current power source supply units do not supply power, the direct-current power source supply units power the computer units. The embodiment further discloses a data center with the power source supply system.

Description

technical field [0001] The present invention generally relates to the field of data processing systems, and 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. A data center is a large centralized computing facility that is expensive to construct and usually includes a large number of computer systems placed in racks. Generally, a data center converts the voltage of a public power supply into a voltage required by the data center through a power supply system to provide power. [0003] figure 1 A configuration of a known data center 100 is described. The data center 100 may be a space in which a data processing system 102 is housed. The data processing system 102 includes one or more computer units 104, such as one or more servers. The one or more computer units 104 are respectively electrically cou...

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.
