Abstract:
Provided is a wireless power transmission device. The wireless power transmission device includes a power coil in which a high frequency current is applied, a transmission coil in which the high frequency current is induced by magnetic induction, the transmission coil configured to generate an non-radiative electromagnetic wave when the transmission coil has the same resonant frequency as an at least one external target device, and a resonant frequency regulator configured to regulate the resonant frequency of the transmission coil. The wireless power transmission device can transmit the power when it has the same resonant frequency as the target device. Therefore, the overheating due to an eddy current may not occur, and the design may be easily varied.
