Device and method for system power supply management and system with function of power source energy saving management

Abstract

The invention discloses a device and a method for system power supply management, and a system with a function of power source energy saving management. The device comprises: a single-card energy saving management module, a system energy saving management module, and a power source energy saving management module, wherein the single-card energy saving management module is used to execute single-card energy saving action and generate single-card power variation which is corresponding to the single-card energy saving action, and the single-card power variation is sent to the system energy saving management module before the single-card energy saving action is executed. The system energy saving management module is used to calculate a system's expected power variation according to the single-card power variation after receiving the single-card power variation, and according to the system's expected power variation, the system energy saving management module controls the power source energy saving management module to adjust power output of the system's power module. The device, the method and the system overcome a technical problem of poor power source energy saving control efficiency of a system in the prior art, and achieve technical effects of more accurate power source energy saving control and maximum power source energy saving effect.

Description

technical field [0001] The invention relates to the field of power supplies, in particular to a system power supply management device, a method and a system with a power supply energy saving management function. Background technique [0002] In a general system, in order to ensure that the system can still work normally after a power module fails, there are usually more than one redundant power module working, but the power module itself needs to consume part of the power, so the power consumed by the system will be reduced. increase, and the output efficiency of the power module is not high, so that the maximum utilization of the power module cannot be realized. [0003] In the prior art, in order to reduce system power consumption, firstly detect the change of dynamic power of the system, and then execute related operations of shutting down the redundant power supply module and adjusting the system input bus voltage according to the detected above-mentioned power change, a...

AI Technical Summary

Problems solved by technology

On the one hand, this method of reducing system power consumption needs to detect the change of system dynamic power first, and on the other hand, the energy-saving operation performed on the power module is based on the detected Energy-saving operation relies on a detection process, and because the above-mentioned detection process of system dynamic power changes occurs after the system dynamic power change, this method of reducing system power consumption has a certain hysteresis and cannot be based on the system. Dynamic power changes, timely and accurate voltage regulation and shutdown control of the power module, so the energy saving effect is poor
