Abstract

The invention provides redundant power supply equipment and a computer system. The equipment comprises at least two power supply modules, a first saving module, at least two power detection modules, a switch module and a switch control module, wherein the first saving module is used for saving corresponding relationships between the load and the output efficiency of the power supply modules; the two power detection modules are used for respectively detecting the currently actually required power of corresponding sub-systems; the switch module is arranged between the power supply modules and the two power detection modules; the switch control module is used for controlling the switch module according to the corresponding relationships between the load and the output efficiency of the powersupply modules and the currently actually required power of the sub-systems to convert the connection between the power supply modules and the power detection modules from a first connection to a second connection; and the total power consumption of the at least two power supply modules in the second connection is smaller than that of the at least two power supply modules in the first connection.The redundant power supply equipment makes full use of electric energy.

Description

technical field [0001] The invention relates to the technical field of power supply, in particular to redundant power supply equipment and a computer system. Background technique [0002] With the continuous improvement of people's living standards, the consumption of electric energy is also in a state of continuous growth. Under the current situation, due to the continuous growth of electric energy consumption in various fields, the supply of electric energy is in short supply, so it is necessary to improve the efficiency of electric energy use. [0003] However, in the field of electricity use, the waste of electric energy in the computer field is quite alarming. According to statistics from Climate Salvers, the efficiency of ordinary personal computers is only 50%, while the efficiency of servers running 24 hours a day can only reach 70%. [0004] In the current computer field, there are already more and more computer systems integrating two or more subsystems, and a re...
