Problems solved by technology

However, in the current use of multi-phase power supplies, if the load changes suddenly, the number of power supply phases needs to be switched accordingly, and the switching process of the number of power supply phases is slow, which easily causes large currents to be concentrated on the single-phase power supply, resulting in MOS tubes and other devices. damage problem

Abstract

The invention discloses a power supply switching method, device and system, and the method comprises the steps: obtaining an output current of a power supply module, obtaining an analog voltage signal generated based on an AC signal of the output current of the power supply module, and controlling the switching of a current-phase power supply of the power supply module based on the output current and the analog voltage signal.

Description

technical field [0001] The present application relates to the field of power switching, in particular to a power switching method, device and system. Background technique [0002] Multi-phase power supplies are common in graphics processor GPU applications. However, in the current use of multi-phase power supplies, if the load changes suddenly, the number of power supply phases needs to be switched accordingly, and the switching process of the number of power supply phases is slow, which easily causes large currents to be concentrated on the single-phase power supply, resulting in MOS tubes and other devices. Corruption problem. Contents of the invention [0003] In view of this, the present application provides a power switching method, device and system, the specific scheme of which is as follows: [0004] A power switching method, comprising: [0005] Obtain the output current of the power module; [0006] Obtaining an analog voltage signal generated based on an AC ...
