APPARATUS AND METHOD FOR WIRELESS POWER TRANSMISSION

摘要

An apparatus and method for controlling a magnetic field when power is wirelessly transmitted are provided. According to one general aspect, a wireless power transmitter may include: a source resonator configured to wirelessly transmit power to a target device including at least one sub-resonator located there within; and a magnetic field distribution controller configured to control the distribution of the magnetic field within the resonator based the resonance frequency of the at least one sub-resonator and the resonance frequency of the source resonator.
