Abstract

The embodiment of the invention discloses a power supply device, a charging method and system, and a computer readable storage medium. The power supply device comprises a rectification module used forrectifying an AC voltage to obtain a first pulsating DC voltage, a primary conversion circuit, a secondary conversion circuit and a valley fill circuit, wherein the primary conversion circuit is connected with the rectification module and is used for carrying out isolation conversion on the first pulsating DC voltage to obtain a second pulsating DC voltage; the secondary conversion circuit is connected with the primary conversion circuit and is used for converting the second pulsating DC voltage to obtain a stable DC voltage; and the valley fill circuit is connected with the primary conversion circuit and is used for providing electric energy for the input of the primary conversion circuit when the voltage value of the first pulsating DC voltage is lower than a first voltage threshold value so as to increase a valley voltage of the first pulsating DC voltage. According to the power supply device, the charging method and system, and the computer readable storage medium, the size of thepower supply device can be reduced.

Description

technical field [0001] The present application relates to the technical field of charging, and in particular to a power supply device, a charging method and system, and a computer-readable storage medium. Background technique [0002] With the rapid development of electronic technology, more and more forms of electronic products appear on the market, and electronic products have become an indispensable part of users' lives. Many electronic products (such as mobile phones, wearable devices, etc.) on the market need to be charged frequently in order to ensure normal operation. Currently, devices (such as adapters, etc.) capable of providing power for electronic products are usually bulky and inconvenient to carry. How to reduce the size of the device providing power has become an urgent problem to be solved. Contents of the invention [0003] The embodiment of the present application discloses a power supply device, a charging method and system, and a computer-readable sto...
