Abstract

The embodiment of the invention discloses a power supply device, and a charging method and system. The power supply device comprises a rectification module used for rectifying an AC voltage to obtain a first pulsating DC voltage, a conversion module used for converting the first pulsating DC voltage to obtain a stable DC voltage, and a valley filling circuit which is connected with the rectification module and the conversion module, and is used for boosting the first pulsating DC voltage output by the rectification module when the voltage value of the first pulsating DC voltage is greater than a first voltage threshold value, and storing energy based on the boosted first pulsating DC voltage; and when the voltage value of the first pulsating DC voltage is smaller than a second voltage threshold value, electric energy is provided for the conversion module so that a trough voltage of the first pulsating DC voltage input to the conversion module is increased. According to the power supply device, the charging method and system, the size of the power supply device can be reduced, and the stability of the output voltage of the power supply device is ensured.

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 a system. 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 a system, which can reduce the volume of the power supply device and ensu...
