Abstract

The present invention provides a power supply adjustment method and electronic equipment, wherein the method includes: acquiring working state information; and adjusting the output voltage of a power supply based on the working state information. The invention has the effect of being able to adaptively control the output voltage of the power supply equipment according to the working state of the electronic equipment, so as to realize energy saving and environmental protection.

Description

technical field [0001] Embodiments of the present invention relate to the field of energy-saving control, and in particular, to a power supply adjustment method and electronic equipment. Background technique [0002] With the concept of energy saving and environmental protection and the development of technology, various countries and the International Electrotechnical Commission have higher and higher requirements for the energy saving of electronic equipment. For example, ES7.0 now requires the power supply to be upgraded from ES6.0 bronze (85%) to gold (90%), and ErP 2013 requires the overall shutdown loss to be reduced from 1.0W to 0.5W, and the adapter to be reduced by 0.5W under no load. to 0.21W and so on. [0003] In view of the above situation, the technical means adopted in the prior art are usually to improve the efficiency of the power supply (including standby and power-on efficiency) as much as possible, or to improve the D2D efficiency of the motherboard side...
