Embodiment Construction

[0016] The existing switching power supply is usually provided with a voltage divider module and an input voltage detection module. Wherein, the voltage dividing module can divide the voltage of the input terminal of the switching power supply to provide input voltage for other modules. The input voltage detecting module can be connected with the output end of the voltage dividing module, so as to detect the output voltage of the voltage dividing module.

[0017] In the existing switching power supply, the total resistance of the voltage divider module is usually fixed and cannot be changed according to the change of the load, resulting in high overall power consumption of the switching power supply.

[0018] In addition, the switching power supply has many protection functions, such as overvoltage and undervoltage protection, overpower protection, etc. These protection functions avoid damage to the power integrated IC and the entire switching power supply. In addition, the s...

Abstract

The invention discloses a switching power supply, a control method and device thereof and a computer readable storage medium. The method comprises the following steps: acquiring load information of the switching power supply; and adjusting at least one of the voltage dividing result of a voltage dividing module and the working frequency of the input voltage detection module based on the load information of the switching power supply. By adopting the scheme, the power consumption of the switching power supply can be effectively reduced.

Description

technical field [0001] The present invention relates to the technical field of electronic circuits, in particular to a switching power supply and its control method, device, and computer-readable storage medium. Background technique [0002] With the rapid development of the electronic information industry, switching power supplies are widely used in computers, electrical equipment, instruments, lighting, medical equipment, military equipment and other fields. Generally, a switching power supply converts an external alternating current (such as 220V, 380V, etc.) into a stable direct current to supply the load. [0003] However, the overall power consumption of the existing switching power supply is relatively high, and it is difficult to meet the user's demand for low power consumption. Contents of the invention [0004] The problem to be solved by the invention is: how to reduce the power consumption of the switching power supply. [0005] In order to solve the above pr...
