WIRELESS POWER TRANSMITTING DEVICE CAPABLE OF MINIMIZING THE CHANGE OF A Q-FACTOR OR RESONANT FREQUENCY OF A POWER RESONATOR

摘要

PURPOSE: A wireless power transmitting device is provided to reduce the influence of a magnetic field on peripheral devices and control the direction of a near field. ;CONSTITUTION: A source unit includes a power resonator(111) and transmits power to a target device(120) by wireless. A near field control unit controls the direction of the magnetic field of the power resonator by considering the position of the target device and has a HIS(High Impedance Suffice) property.;COPYRIGHT KIPO 2011
