WIRELESS POWER FEEDING DEVICE

WIPO Patent Application WO/2019/151225

A1

The present disclosure provides a wireless power feeding device capable of performing wireless power feeding efficiently with respect to a power reception coil embedded at the center of a spherical power reception device. The wireless power feeding device is provided with: a holding part 10a which holds a power reception device 2; a power transmission coil 11; a driver circuit 13 which supplies the power transmission coil 11 with a high-frequency current to generate a magnetic flux for performing wireless power feeding with respect to a power reception coil 24; and a wireless data reception means for receiving data periodically transmitted from a wireless data transmission means. The power transmission coil 11 is positioned with respect to the holding part 10a in such a way that, when the power reception device 2 is held by the holding part 10a with a mark M attached to a surface of the power reception device 2 oriented in a predetermined direction, the respective axes of the power reception coil 24 and the power transmission coil 11 become parallel to each other.
