Abstract
Provided is a wireless charging apparatus for performing wireless charging of an electronic device including a receiving coil located in a three-dimensional (3D) wireless charging zone using a plurality of transmitting coils arranged in the 3D wireless charging zone and at least one power source configured to supply a current to the plurality of transmitting coils.
Claims12
A wireless charging apparatus comprising:
- a plurality of transmitting coils included in a wireless charging zone in a three-dimensional (3D) form;
- and
- at least one power source configured to supply a current to the plurality of transmitting coils,
- wherein the at least one pair of transmitting coils are configured to form a quiet zone indicating a magnetic field having an equalized energy density in the wireless charging zone.
