    摘要: 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.

    摘要: Provided is a power transmission device including a transmission unit and a reception unit. The reception unit includes an overvoltage protection circuit and provides a feedback signal to the transmission unit. The transmission unit controls intensity of power wirelessly transmitted to the reception unit with reference to the feedback signal to control power consumption of the overvoltage protection circuit. The overvoltage protection circuit includes a detection unit and a current control unit. The detection unit detects an input voltage and a first current to generate a control signal. The current control unit controls a second current with reference to the control signal. Herein, the second current is controlled so that a ratio of the input voltage to a sum of the first and second currents is kept constant.
