Title:
ADAPTER AND CHARGE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/133399
Kind Code:
A1
Abstract:
An adapter and a charge control method, the adapter (10) comprising: a power conversion unit (11); a voltage feedback unit (12); a current feedback unit (13); and a power adjustment unit (14). An input terminal of the power adjustment unit (14) is connected to an output terminal of the voltage feedback unit (12) and an output terminal of the current feedback unit (13). An output terminal of the power adjustment unit (14) is connected to the power conversion unit (11). The power adjustment unit (14) is used to receive a voltage feedback signal and a current feedback signal and to stabilize an output voltage and an output current of the adapter (10) in the case where the voltage feedback signal indicates that the output voltage of the adapter reaches a target voltage, or the current feedback signal indicates that the output current of the adapter reaches a target current. The adapter (10) can improve the safety in the charging process.
