Abstract: A wireless power transmitting device for wirelessly transmitting power to an electronic device is provided. The wireless power transmitting device includes a first coil configured to have a first number of windings and to receive power to be transmitted to the electronic device, thereby generating a magnetic field; and a second coil configured to have a second number of windings, which is different from the first number of windings, wherein an induced electromotive force generated, based on the magnetic field generated from the first coil, in the second coil is used for operation of at least one hardware component of the wireless power transmitting device, and wherein a ratio of a voltage applied to the first coil to a voltage applied to the second coil is determined by a ratio of the first number of windings to the second number of windings.
