A method, device, system and computer for reducing power loss of chopper

Abstract

The invention discloses a method for reducing the power loss of a chopper, which includes obtaining the input voltage and output voltage of the chopper; judging whether the ratio of the input voltage to the output voltage exceeds a preset threshold; if so, controlling the input voltage to approach the Adjust to the preset value in the direction of the output voltage. In the present invention, when the ratio of the input voltage to the output voltage exceeds the preset threshold, the input voltage can be controlled to adjust to the preset value in the direction of approaching the output voltage. Since the input voltage is close to the output voltage, the device loss is small, The conversion efficiency is high, so the invention reduces the power loss of the chopper, improves the conversion efficiency, reduces the waste of power energy, and prolongs the service life of related devices. The invention also provides a device, a system and a notebook computer for reducing the power loss of the chopper, which have the same beneficial effect as the method for reducing the power loss of the chopper.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for reducing the power loss of a chopper, and also relates to a device, a system and a notebook computer for reducing the power loss of a chopper. Background technique [0002] A chopper is a DC voltage converter commonly used in switching power supplies. Whether it is a chopper based on a buck converter circuit, a boost boost converter circuit, or a buck or boost Buck-Boost converter circuit, its When the DC voltage is converted, components such as switching tubes or inductors inside the chopper will consume a large amount of electric energy, and the utilization rate of electric energy is low, resulting in waste of electric energy and reducing the life of the device. [0003] Therefore, how to provide a solution to the above technical problems is a problem that those skilled in the art need to solve at present. Contents of the invention [0004] The object of the...
