Abstract
The disclosure provides a wireless power transmitting apparatus and a method for wirelessly transmitting power by the wireless power transmitting apparatus. The wireless power transmitting apparatus according to an example embodiment comprises: a power amplifier; a coil connected to the power amplifier and configured to generate an electromagnetic field based on power received from the power amplifier; an impedance sensing circuit connected between the power amplifier and the coil; at least one auxiliary coil electromagnetically coupled to the coil; and a controller, wherein the controller may be configured to: identify a change in impedance, from a signal sensed through the impedance sensing circuit, and adjust an operation setting of the at least one auxiliary coil based on the identified change in impedance.
