Title:
WIRELESS CHARGING APPARATUS, ELECTRONIC DEVICE AND WIRELESS CHARGING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/226615
Kind Code:
A9
Abstract:
A wireless charging apparatus, an electronic device and a wireless charging control method, which relate to the technical field of terminals and the technical field of wireless charging. The wireless charging apparatus is used for wirelessly charging the electronic device. The wireless charging apparatus comprises an inverter, a transmitting-end resonance circuit and a transmitting-end controller, wherein the inverter is used for converting a direct current into an alternating current and then transmitting same to the transmitting-end resonance circuit; the transmitting-end resonance circuit comprises a transmitting-end resonance capacitor and a power transmitting coil, which are connected in series; the transmitting-end controller is used for acquiring the current quality factor of the transmitting-end resonance circuit and for increasing the working frequency of the inverter when it is determined, by using the current quality factor, that there is metallic foreign matter between the wireless charging apparatus and the electronic device. By means of the solution provided in the present application, the working frequency of an inverter is increased, such that the efficiency of wireless charging can be improved, and thus the wireless charging time is prevented from being prolonged, thereby improving the user experience.
