Title:
WIRELESS POWER TRANSMISSION DEVICE FOR DETECTING HUMAN BODY, AND OPERATING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/229198
Kind Code:
A1
Abstract:
A wireless power reception device according to various embodiments comprises: a power transmission coil; a first circuit electrically connected to the power transmission coil so as to provide first power of a first frequency to the power transmission coil; a sensing antenna for detecting a human body; a second circuit electrically connected to the sensing antenna; and a controller, wherein the controller can be configured to: control the first circuit so that the first power of the first frequency is provided to the power transmission coil; control the second circuit so that second power of a second frequency, which differs from the first frequency, is provided to the sensing antenna while the first power is provided to the power transmission coil; acquire, from the second circuit, at least one parameter based on at least one sensing result measured at at least one point of the second circuit; confirm the distance from the sensing antenna to a human body adjacent to the sensing antenna on the basis of the at least one parameter; and control the first circuit so as to adjust the magnitude of the first power on the basis of the distance from the sensing antenna up to the human body.
