摘要： 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.

摘要： The wireless charging device according to an embodiment may comprise a shielding assembly where a shield, a first coil for power transfer by magnetic inductive coupling, and a bracket are formed, an NFC coil fixed to the bracket, and a main PCB including an inverter that converts DC power into AC power and supplies it to the first coil. The bracket may be formed outside the first coil. The shielding assembly may further include a coil connector for connecting the first coil and the NFC coil to the main PCB. The coil connector may consist of a plurality of protruding pins, and the plurality of protruding pins may be inserted into holes formed at corresponding positions on the main PCB so that the first coil and the NFC coil are electrically connected to the main PCB.
