Abstract:
The present disclosure relates to a wireless power transfer method, a wireless power transmitter and a wireless charging system in a wireless power transfer field. That is, a wireless power transmitter configured transfer power to a wireless power receiver in a wireless manner, the transmitter configured to a first coil configured to convert a current into a magnetic flux, a second coil configured to be adjacent to the first coil on a plane, a third coil configured to have a different shape from the first and second coils and have at least part thereof which overlaps the first and second coils, respectively, and a controller configured to determine a coil to be activated among the first, second and third coils.
