Abstract

The embodiment of the invention discloses a power supply adaptation device, a control method thereof, and a control device thereof. The method comprises the steps that: a communication protocol chip obtains an input voltage value through a first detection end; the communication protocol chip obtains a target voltage value through a second detection end; the communication protocol chip determines voltage adjustment information according to the target voltage value and the input voltage value; a voltage conversion chip carries out voltage conversion according to the voltage adjustment information such that the voltage value of a power output interface is matched with the target voltage valve. According to the embodiment of the invention, a problem of resource waste caused by a condition that a traditional DC adapter can not be applied to electronic equipment with a TYPE-C type USB interface in the prior art is solved, thus the same traditional DC adapter can complete a task of charging a variety of electronic equipment, and the utilization rate of the traditional DC adapter is improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of chargers, and in particular, to a power adapter device, a control method and a device. Background technique [0002] With the popularization of TYPE-C USB (Universal Serial Bus, universal serial bus) interface, the adapter of TYPE-C USB interface based on USBPD (USB Power Delivery, charging protocol) communication protocol is being used more and more . [0003] Adapters to legacy interfaces are bound to continue to coexist for some time. When users do not discard the original adapter, they need to convert the traditional power adapter into an adapter based on the USB PD communication protocol, so as to be applicable to the charging needs of various electronic devices with TYPE-C USB interface. [0004] However, ordinary traditional power adapters cannot be directly converted into USB PD power, thus causing a waste of resources. Contents of the invention [0005] Embodiments ...
