Title:
ELECTRONIC DEVICE FOR WIRELESS POWER TRANSMISSION AND RECEPTION AND OPERATION METHOD OF SAME
Document Type and Number:
WIPO Patent Application WO/2024/034816
Kind Code:
A1
Abstract:
An electronic device may comprise: a converter that is configured to perform DC/DC power conversion; a power conversion circuit that is electrically or operatively connected to the converter and configured to perform AC/DC power conversion; a coil that is electrically or operatively connected to the power conversion circuit; a motion sensor that is configured to sense the motion of the electronic device; and a controller that is operatively connected to the converter, the power conversion circuit, or the motion sensor. The controller may be configured to check the impedance variation at one or more points in the electronic device. The controller may be configured to check the motion variation of the electronic device via the motion sensor on the basis that the impedance variation is greater than a first reference value. The controller may be configured to set a delay time on the basis that the motion variation is greater than a second reference value. The controller may be configured to transmit first driving power to an external electronic device via the coil at the end of the delay time. Various other embodiments are possible.
