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

Abstract

Disclosed are a device and method for system power supply management and a system having a power supply energy-saving management function. The device comprises: a single-board energy-saving management module, a system energy-saving management module, and a power supply energy-saving management module. The single-board energy-saving management module is for use in executing a single-board energy-saving action, in generating a single-board power variation amount corresponding to the single-board energy-saving action, and in transmitting the single-board power variation amount to the system energy-saving management module before executing the single-board energy-saving action; the system energy-saving module is for use in, when the single-board power variation amount is received, calculating an expected power variation amount on the basis of the single-board power variation amount, and in controlling, on the basis of the expected power variation amount of the system, the power supply energy-saving management module to adjust a power output of the power supply module in the system. The present invention solves the technical problem in the prior art of poor efficiency in power supply energy-saving control, achieves the technical effects of increased accuracy in power supply energy-saving control and of maximized power supply 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...

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
