Problems solved by technology

When the performance status of the high-density GPU is converted to each other, the current demand of the high-density GPU will change instantaneously. The output voltage of the powered PSU temporarily drops or overshoots, which triggers the PSU to perform under-voltage protection or over-voltage protection. In this case, it will cause the high-density GPU to malfunction
At present, there is no effective solution to this technical problem

Embodiment approach

[0041] Based on the above embodiments, this embodiment further explains and optimizes the technical solution, please refer to Figure 4 , Figure 4 A structural diagram of another PSU applied to a high-density GPU provided by an embodiment of the present invention. As a preferred embodiment, the above-mentioned PSU applied to high-density GPU also includes:

[0042] The power protection module 15 is configured to limit the pulse width of the PWM driving signal output by the PWM control module 13 within a preset range.

[0043] It is understandable that when the required current of the high-density GPU exceeds the limit design specification of the PSU, the transient peak current of the high-density GPU will easily exceed the compensation superposition, which will not only damage the switching power module in the PSU, but also Can cause damage to high-density GPUs. Therefore, in this embodiment, in order to avoid the occurrence of the above situation, a power protection modul...

Abstract

This application discloses a PSU applied to high-density GPUs, including: an energy storage module, a power switch module, and a PWM control module, which are used to adjust the AC input current to The first reference voltage; or when it is detected that the current demand of the high-density GPU decreases, the AC input current is adjusted to the second reference voltage; the power factor correction module is used to control the energy storage according to the first reference voltage or the second reference voltage The module releases energy or absorbs energy, so that the power switch module drives the high-density GPU to work at a preset voltage. Because the PSU can adjust the AC input current according to the current demand of the high-density GPU, and enables the power switch module to drive the high-density GPU to work at a preset voltage, thus avoiding the high-density GPU's need for switching between performance states. A downtime failure occurred.

Description

technical field [0001] The invention relates to the technical field of servers, in particular to a PSU applied to high-density GPUs and a power supply system. Background technique [0002] With the rapid development of artificial intelligence technology, people have higher and higher requirements for the graphics processing capabilities of rack servers in data centers, so a large number of high-performance GPUs (Graphics Processing Unit, graphics processor), that is, form a high-density GPU. [0003] See figure 1 , figure 1 It is a schematic diagram of the working principle of the PSU in the prior art when powering the high-density GPU. In this PSU (Power Supply Unit, power supply), the AC input current passes through the power factor correction module and the energy storage module, and the AC input current is converted to 380VDC, and the 380VDC is converted into high-frequency pulse AC through the power switch module, wherein the power switch module Controlled by the PW...
