摘要
The present specification which relates to a wireless power transmission device and a control method, capable of transmitting and receiving power wirelessly comprises a power supply unit for supplying power to a receiving device to transmit power wirelessly; and a power transmission control unit for, periodically generating a waveform with a particular frequency, measuring an attenuation coefficient of the waveform at each cycle, measuring a variation in the attenuation coefficient at each cycle, and determining the type of an external material. The present invention has a technical feature wherein the power transmission control unit determines whether to transmit power wirelessly to the receiving device on the basis of the type of the external material.

On the other hand, the power conversion unit 111 may further include a circuit for controlling the characteristics of a used frequency, an applied voltage, an applied current or the like to form the wireless power signal.
The power transmission control unit 112 controls each of the constituent elements included in the power transmission unit 110 The power transmission control unit 112 may be implemented to be integrated into another control unit (not shown) for controlling the wireless power transmitter 100.
