  • Wireless charging apparatus for preventing magnetic field cancellation between adjacent coils
    Patent number: 11381117
    Abstract: Disclosed herein is a wireless charging apparatus for preventing cancelation of magnetic fields generated between a plurality of adjacent transmission coils by placing a repeater on the plurality of transmission coils, the wireless charging apparatus including a plurality of transmission coils spaced the same distance apart from a reference point, and a repeater placed on the plurality of transmission coils to be overlapped with each of the plurality of transmission coils with respect to the reference point that is a center, wherein a coupling coefficient between each of the plurality of transmission coils and the repeater is higher than a coupling coefficient between the plurality of transmission coils.
    Type: Grant
    Filed: February 21, 2020
    Date of Patent: July 5, 2022
    Assignee: LG ELECTRONICS INC.
