Abstract

Disclosed in the embodiment of the present invention is a power supply method comprising: rectifying a second path of alternating current, and converting the second path of alternating current to a second path of high voltage direct current; inputting a third path of high voltage direct current in a DC / DC (direct current / direct current) module when the second path of high voltage direct current is abnormal; inputting the second path of high voltage direct current in the DC / DC module when the second path of high voltage direct current is normal; and converting the second path of high voltage direct current or the third path of high voltage direct current to a low-voltage direct current by the DC / DC module, and outputting the low-voltage direct current.

Description

technical field [0001] The invention relates to the technical field of electronic communication, in particular to a power supply method and device. Background technique [0002] see figure 1 , the existing data center (or computer room) adopts the AC power supply method. In order to ensure the reliability of the power supply and distribution of the entire data center equipment, two sets of power supply systems are used for power supply. ATS (Automatic Transfer Switches, automatic transfer switch) switch equipment to supply power to the subsequent load. [0003] The alternating current output by the ATS is divided into two branches A and B after passing through the AC (Alternating Current) power distribution panel. Branch A is input to the UPS (Uninterruptible power supply) system A in the computer room, and branch B is input to the UPS in the computer room. The AC power output by UPS system B, UPS system A and UPS system B passes through the power distribution cabinet and ...
