Abstract
The present invention relates to a method and an apparatus for wirelessly transmitting power. A method for wirelessly transmitting power according to an embodiment can measure and store signal strength values corresponding to inductive coupling degrees with a secondary coil of a receiving apparatus sequentially with respect to two or more primary coils included in two or more resonance circuits, select a primary coil related to a largest signal strength value among the signal strength values as an operating coil, adjust a reference value of a power loss value which becomes a basis for entering a mode for detecting power loss based on a difference between a signal strength for a primary coil adjacent to the operating coil and a signal strength value for the operating coil, and transmit power to a wireless power receiving apparatus through the operating coil.
