Example Embodiment

[0019] The present invention will be further described below in conjunction with the drawings.

[0020] According to the corresponding relationship between the resonant voltage and the resonant frequency of the wireless charging system receiving end in the Qi standard, when the wireless charging distance increases, in order to ensure that the wireless charging receiving end obtains sufficient energy during the Ping phase to enable the wireless charging transmitter to establish communication with the receiving end, you can Reduce the frequency of the Ping phase. At the same time, in order to avoid the problem that the wireless charging receiver in the Ping phase caused by the small wireless charging distance causes protection and the establishment of communication failure, two or more Ping phase frequency points can be set to work in turn to ensure that the system is wirelessly charged. Communication can be established normally within the distance.

[0021] The principle block...

Abstract

The invention discloses a wireless charging system. The system comprises a wireless charging receiving module. The wireless charging receiving module possesses a MCU and a voltage sampling component. The voltage sampling component carries out sampling on a voltage after rectification and voltage stabilization. When a dynamic load is adjusted, voltage abnormity is fed back to the MCU. The MCU controls an output voltage. The invention also discloses a wireless charging method. Two or more Ping phase frequency points are arranged to carry out work by turns. By using the system and the method, problems that a dynamic load response is abnormal and a wireless charging distance is small, which exist in a current wireless charging system, are solved; a damage of the wireless charging system to receiving end circuit component and an assembling problem of office furniture are avoided.

Description

technical field [0001] The invention relates to the field of wireless charging, in particular to a wireless charging system and method. Background technique [0002] With the promotion and popularization of wireless charging technology and the increase of consumer electronics products, more and more wireless chargers have begun to enter the office field. The combination of wireless charging equipment and office furniture can bring users a convenient charging or power supply experience while keeping the furniture desktop clean and beautiful. These will undoubtedly bring new points of differentiation to the furniture industry and will certainly promote the development of the furniture industry. Good development. [0003] Wireless charging mainly includes inductive wireless charging and resonant wireless charging. Inductive wireless charging is relatively mature, and there are already many products on the market, typical of which are various mobile phone wireless chargers. W...
