AI Technical Summary

Problems solved by technology

However, under the architecture of the AI ​​server, the overall power consumption is relatively large, and the efficiency of AC / DC conversion of 12V voltage is low
Secondly, if all 12V power supply is used, the current needs to reach hundreds of amps, so the current transmission loss is large and the efficiency is reduced

Abstract

The application discloses a server power board, power supply system and method. Wherein, the power board includes: a power management unit, an input interface, a step-down circuit, a 48V voltage output interface and a 12V voltage output interface; the input interface is used to connect the output end of a rectifier, and the rectifier is used to rectify the alternating current into 48V direct current; the 48V voltage output interface is used to provide the 48V direct current to the main board of the graphics processor GPU; the voltage step-down circuit is used to input the input interface under the control of the power management unit The 48V direct current is stepped down to 12V direct current and sent to the 12V voltage output interface; the 12V voltage output interface is used to provide the 12V direct current to the server. The power board provided by this application can meet the power requirements of the main board of the traditional server and the main board of the AI ​​server at the same time, and has low power consumption.

Description

technical field [0001] The invention relates to the field of computer science and technology, in particular to a server power board, power supply system and method. Background technique [0002] With the development of artificial intelligence (AI, Artificial Intelligence), AI servers are getting more and more attention. The difference between an AI server and a traditional server is the introduction of a graphics processing unit (GPU, Graphics Processing Unit), and the power supply of the GPU motherboard is mainly 48V, while the power supply of the traditional server motherboard is 12V. Therefore, the power supplies of different boards of the AI ​​server are different. [0003] The traditional server power supply converts 220V AC power into 12V DC power for the server through the rectifier AC / DC. When the overall power consumption of the server is low, this method is simple to connect, convenient to install, and highly practical. However, under the architecture of the AI ...
