Document Type and Number:
Japanese Patent JP2023139128
Kind Code:
A
Abstract:
To provide a wireless power transmitter that is capable of accurately detecting foreign objects, and can not only more effectively and accurately detect foreign objects but also minimize unnecessary charging interruptions.SOLUTION: A wireless power transmission control method for a wireless power transmitter includes: a first packet receiving step of receiving a foreign object detection status packet; a first determination step of determining whether a foreign object exists based on the foreign object detection status packet; and a power control step of controlling power based on a determination result in the first determination step. The power control step includes a first power transmission mode in which a first power is transmitted when it is determined that there is no foreign object as the determination result in the first determination step, and a second power transmission mode in which a second power is transmitted when it is determined that there is a foreign object as the determination result in the first determination step.SELECTED DRAWING: Figure 11
