Abstract

The invention discloses a power supply capable of automatically monitoring service life. The power supply comprises a temperature monitoring unit, a ripple voltage monitoring unit and a processing unit, wherein the temperature monitoring unit monitors the temperature inside the power supply, and the ripple voltage monitoring unit monitors ripple voltage of a power supply electrolytic capacitor. The processing unit acquires a ripple voltage in initial temperature and a ripple voltage in working temperature when the power supply is utilized at the first time, the ripple voltage in initial temperature and the ripple voltage in working temperature are converted into equivalent ripple voltages in standard temperature respectively, and the equivalent ripple voltage corresponding to the ripple voltage in process of working is compared with the equivalent ripple voltage corresponding to the initial ripple voltage so as to judge whether the power supply reaches the service life or not. The invention further relates to a method for monitoring the service life of the power supply, which can accurately monitor and estimate the power supply in operation conveniently, so that a user is promoted to avoid the loss caused by the unexpected power outage when the power supply is close to the service life.

Description

technical field

[0001] The invention relates to a power supply capable of automatically monitoring the service life and a method for monitoring the service life of the power supply. Background technique

[0002] In fields such as computers and electronic commerce, devices such as servers and storage devices are widely used, and power supplies are key components of these devices. The shutdown of equipment caused by unexpected power failure will cause great losses, even irreparable disasters. Therefore, the service life of the power supply should be monitored, so that users can be reminded in advance when the power supply is approaching its service life to prevent losses.

[0003] As disclosed in the Chinese patent application document with the application number 201010156582.4 and the application date of April 27, 2010, the current general method of monitoring the service life of the power supply is to detect the ripple current value of the electrolytic capacitor in the power...
