A backup power module and server power supply

Abstract

The invention discloses a backup power module, comprising: a battery, a backup power logic unit, and a first switch arranged between the battery and the power supply input end of the backup power logic unit; wherein, the power supply input end of the backup power logic unit is also It is connected with the first output end of the AC power rectification and step-down module. By setting the first switch controlled by the second output terminal of the AC power rectification and step-down module, it is realized that when the AC power supply works normally, the power supply of the battery to the backup logic unit is cut off, and the AC power supplies power to the backup logic unit. After the accidental power failure of the AC power supply, it can control the conduction between the battery and the backup logic unit. At this time, the battery supplies power to the backup logic unit, so that the battery is not wasted when the AC power supply is effectively powered. Compared with the existing technology The number of charging and discharging of the battery is reduced, and the service life of the battery is prolonged. The invention also discloses a server power supply, which has the above beneficial effects.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a backup power module and a server power supply. Background technique [0002] In electronic devices such as storage and servers, batteries are often used for backup power. When the system is abnormally powered down, it is switched to battery power to provide power for the system instead of AC power to ensure the normal operation of the system and avoid data loss. [0003] The backup power switching logic is implemented by the backup power logic unit. In order to ensure the reliability of backup power switching, the power of the backup power logic unit of the traditional backup power module is provided by the battery, and this architecture causes the backup power module to use the power of the battery itself when the AC power supply is normal, resulting in The power consumption of the battery is equivalent to increasing the number of battery charging and discharging and r...
