Abstract:
A wireless power apparatus includes: a power receiver coil which receives power, as magnetic field energy, from a power transmitter coil by magnetic field resonance produced between the power transmitter coil and the power receiver coil; a power pickup coil which derives power from the power receiver coil by electromagnetic induction; a detector which detects current flowing through the power pickup coil; and a controller which controls a coupling strength between the power pickup coil and the power receiver coil based on the current detected by the detector.
