A kind of power supply and server

Abstract

The present invention provides a power supply and a server. The power supply includes: first and second power supplies; the input terminal of the voltage detection chip is connected to the first and second power supply; the input terminal of the first voltage conversion circuit is connected to the voltage detection The first output terminal of the chip and the input terminal of the second voltage conversion circuit are connected to the second output terminal of the voltage detection chip; the control terminal of the first switch chip is connected to the first enabling terminal of the voltage detection chip, and the input terminal is connected to the first enabling terminal of the voltage detection chip The output end of a voltage changing circuit, the output end is connected to the power supply end, the control end of the second switch chip is connected to the second enable end of the voltage detection chip, the input end is connected to the output end of the second voltage changing circuit, and the output end is connected to to the power supply terminal, wherein the voltage detection chip enables the first enable terminal or the second enable terminal according to the voltage value of the power supply to control the opening or closing of the first and second switch chips. Through the invention, stable voltage output can be provided for the board when the power supply voltage is unstable.

Description

technical field [0001] The field relates to the field of computers, and more particularly relates to a power supply and a server. Background technique [0002] The server is a kind of high-performance computer. As a node of the network, it stores and processes 80% of the data and information on the network. Therefore, it is also called the soul of the network. With the development of the Internet, servers have become more and more indispensable. Product quality requirements are getting higher and higher. [0003] Server motherboards, including circuit boards of all electronic products, require a stable power supply for normal operation. Only when the power supply is stable and the performance is good, can the back-end equipment realize its functions better. If the power supply is unstable, there may be downtime, the machine needs to be restarted, and data loss, or the board card may be damaged, causing heavy losses. [0004] Most of the current power supply boards use 12V...

AI Technical Summary

Problems solved by technology

If the power supply is unstable, there may be downtime, the machine needs to be restarted, and the data will be lost. In severe cases, the board card may be damaged, causing heavy losses.

[0004] Most of the current power supply boards use 12V redundant power supply to provide 12V DC input, and there are also 48V or 54V chassis copper bus power supply, which is only suitable for working in laboratories or computer rooms, not suitable for remote areas or outdoors where the environment is poor and the voltage is not stable enough.

However, through POE (Power over Ethernet) power supply method, the power supply structure is relatively simple, and it cannot work under low voltage conditions.
