PURPOSE: A wireless power transmitting device of an electromagnetic field resonance method is provided to precisely compensate the change of a resonant frequency of an electromagnetic field resonator by automatically controlling a tuner of the electromagnetic field resonator of a transmission unit using a reflection wave detector and a microcontroller. CONSTITUTION: A transmission unit(310) transmits power by wireless using an electromagnetic file resonance method and includes an AC signal generator(305), an electromagnetic field generator(311), and a transmission side electromagnetic field resonator(312). The transmission side electromagnetic field resonator reinforces a time variant electromagnetic field generated from the electromagnetic field generator. A receiving unit(320) receives power transmitted from the transmission unit by wireless. The receiving unit includes an electromagnetic field resonator(321), a rectifier(322), and a charger(323). |
