More Information
Summary:PURPOSE: An electronic device, a wireless power transmitting device, and a power transmitting method thereof are provided to prevent the overheat due to an eddy current by transmitting power in the same resonant frequency. CONSTITUTION: A current of a high frequency is inputted to a power coil(140). A transmission coil(160) induces the current of the high frequency with a magnetic induction. The transmission coil generates non-radial electromagnetic wave according to the resonant frequency of at least one target device(200). A resonant frequency controller(180) controls the resonant frequency of the transmission coil. The resonant frequency controller corrects the resonant frequency of the transmission coil by controlling the space between the transmission coils.
