Problems solved by technology

However, the output voltage levels of the two power supply branches are different, the power supply paths are different, and the impedances of the paths are also different. As a result, when the dual power supply is used, the power supply between the two power supply branches is unbalanced, and even some of the power supply branches There is no power supply at all for the output of the circuit. When only one power supply branch is supplying power, if the voltage difference is too large, it will also cause the current reverse series, and the output of one power supply branch will be poured into the other power supply branch, resulting in serious safety hazard

Abstract

The invention discloses an electric control method and device for electronic equipment and the electronic equipment. The method comprises the steps of: obtaining first current information corresponding to first power supply current in a first power supply branch and second current information corresponding to second power supply current in a second power supply branch, wherein the first power supply current and the second power supply current are alternately output so as to supply power for the electronic equipment; judging whether a first ratio of the first power supply current to the secondpower supply current accords with a first preset condition or not according to the first current information and the second current information; and if the judging result is negative, adjusting a dutyratio, for supplying power to the electronic equipment, of the first power supply branch or the second power supply branch according to the first ratio, so as to adjust output of the first power supply current and / or the second power supply current. The method is capable of realizing power supply balance among various power supply branches, and gives full play to power supply ability of each power supply branch.

Description

technical field [0001] The invention relates to the field of circuit control of electronic equipment, in particular to a power control method and device for electronic equipment and electronic equipment. Background technique [0002] At present, electronic equipment such as a computer can be powered by multiple power supply branches for its system, for example, the system of the electronic equipment can be powered by a first power supply branch and a second power supply branch. However, the output voltage levels of the two power supply branches are different, the power supply paths are different, and the impedances of the paths are also different. As a result, when the dual power supply is used, the power supply between the two power supply branches is unbalanced, and even some of the power supply branches There is no power supply at all for the output of the circuit. When only one power supply branch is supplying power, if the voltage difference is too large, it will also c...
