    • 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.
    • 目的:提供一种电子设备,无线电力传输装置及其电力传输方法,以通过以相同的谐振频率发射功率来防止由涡电流引起的过热。 构成:向电力线圈(140)输入高频电流。 传输线圈(160)通过磁感应感应高频电流。 传输线圈根据至少一个目标设备(200)的谐振频率产生非径向电磁波。 谐振频率控制器(180)控制传输线圈的谐振频率。 谐振频率控制器通过控制发送线圈之间的空间来校正发送线圈的谐振频率。
