NFC and wireless charging fusion system and method

Abstract

The invention provides an NFC and wireless charging fusion system and method. The system comprises a wireless charging transmitting end and a wireless charging receiving end, the wireless charging transmitting end comprises a power conversion module and a transmitting end communication control module; the power conversion module comprises a conversion unit and a coil; the conversion unit is respectively connected with the transmitting end communication control module and the coil; the wireless charging receiving end is connected with the transmitting end communication control module and is used for sending a control signal to the conversion unit through the transmitting end communication control module, so that the conversion unit adjusts the output frequency of the conversion unit based on the control signal; the coil is used for working in an NFC communication mode or a wireless charging mode according to different output frequencies; two actions, namely wireless charging and NFC, are completed by using the same coil, whether a battery is charged or related data in a chip is operated through NFC is automatically judged by means of a hardware circuit, the circuit layout and the circuit board area are greatly reduced, and the circuit function efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless charging, and in particular relates to a system and method for integrating NFC and wireless charging. Background technique [0002] The wireless charging coil in the prior art can only be used as wireless charging, and the NFC induction coil can only read and write chip data. Therefore, when wireless charging and NFC functions need to be used simultaneously in the same circuit board, two Independent coils, one for wireless charging and the other for NFC, the area of ​​the two coils will require a lot of space, and as people's demand for miniaturization of electronic equipment is getting higher and higher, the space for electronic equipment It is said to be a very precious resource, and when two coils are placed together, there may be interference between them, thus affecting each other's performance. Contents of the invention [0003] In view of the above-mentioned shortcomings of the prior ar...
