Title:
ELECTRONIC DEVICE FOR TRANSMITTING WIRELESS POWER AND OPERATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/119102
Kind Code:
A1
Abstract:
According to various embodiments, a wireless power transmission device may comprise: a plurality of power transmission coils for transmitting power to a wireless power reception device; a plurality of inverters configured to apply alternating current power to each of the plurality of power transmission coils; at least one communication module using a frequency different from that of the power transmitted from the power transmission coils; and at least one processor, wherein the at least one processor is configured to control each of the plurality of inverters so that first power is sequentially applied to each of the plurality of power transmission coils, receive a first communication signal from the wireless power reception device through the at least one communication module while the first power is sequentially applied to each of the plurality of power transmission coils, perform an operation for identifying a first power transmission coil corresponding to a location of the wireless power reception device from among the plurality of power transmission coils on the basis of a reception time point of the first communication signal and time points at which the first power starts to be applied to each of the plurality of power transmission coils, and control a first inverter corresponding to the first power transmission coil so that second power for charging the wireless power reception device is applied to the first power transmission coil.
