Abstract

The invention provides a charging device. The device comprises an AC-DC conversion module, a Type-c interface module and a microcontroller, wherein the AC-DC module is used for converting an input ACpower supply into direct current to output; the Type-c interface module provides a Type-c interface used for accessing external equipment; the microcontroller is used for confirming the real-time charging requirement of the external equipment when accessing the external equipment by the Type-c interface and transmitting an output voltage control signal according to the real-time charging requirement; and the AC-DC conversion module includes an output voltage regulating circuit, and the output voltage regulating circuit receives the output voltage control signal and regulating the direct current voltage outputted by the AC-DC conversion module into a target voltage. According to the charging device, the conversion efficiency of the AC-DC conversion module is effectively improved, and thus the charging efficiency and the energy efficiency grade of the charging device are improved.

Description

technical field [0001] The invention relates to the field of electronic devices, in particular to a charging device. Background technique [0002] With the increasing popularity of the Type-c interface, more and more manufacturers of mobile phones, tablet computers, and notebooks have transferred the charging interface to the Type-c interface. Future Trends. For the AC-DC power supply, the multi-port Type-C PD output, because the PD output voltage is in a wide range from 3V to 21V, the DC voltage obtained after the conversion of the AC-DC conversion circuit is 22V, so that the PD output requirements In the case of lower voltage, the AC-DC conversion circuit cannot obtain high energy efficiency and high efficiency. [0003] For this reason, it is necessary to propose a new charging device and power supply to solve the problems in the prior art. Contents of the invention [0004] A series of concepts in simplified form are introduced in the Summary of the Invention, which...
