Abstract

The invention discloses a device and method for reducing power consumption of electronic equipment. The method comprises the following steps: obtaining the load state information of a load module; obtaining a voltage regulation signal according to the load state information and a pre-stored logic mapping query table; and regulating the magnitude of the input voltage of the input end of the load module according to the voltage regulation signal. In the invention, the mechanism of logic mapping query table is introduced; and when the load state changes, the magnitude of the input voltage of the load module can be automatically adjusted so as to save energy of the electronic equipment and achieve the purpose of reducing the power consumption.

Description

technical field [0001] The present invention relates to the technical field of low power consumption and energy saving of electronic products, and more specifically, to a device and method for reducing power consumption of electronic equipment. Background technique [0002] With the wide application of electronic products in daily life and work, people's requirements for energy saving and environmental protection of electronic equipment are also constantly increasing. Therefore, how to improve the power efficiency of electronic equipment has attracted more and more attention. [0003] In many applications, electronic equipment can often adjust the input voltage of the load according to the change of the load, so as to achieve the purpose of energy saving, environmental protection, and improvement of electric energy efficiency. Based on this, the energy saving methods of existing electronic equipment are mainly realized through the following two ways: [0004] The first one ...
