Abstract
The present invention provides wireless power transmitting method and apparatus. The wireless power transmitting method according to an embodiment of the present invention may measure a resonance frequency while changing an operating frequency of a resonance circuit, compare the measured resonance frequency with a reference frequency, and wirelessly transmit power when the measured resonance frequency is lower than the reference frequency. The reference frequency may be determined based on two or more among a self resonance frequency of the resonance circuit, a first resonance frequency measured for a receiving device, a second resonance frequency measured for a reference object and a third resonance frequency measured for the receiving device and the reference object.
