1. A wireless power transmitter comprising:
a detecting unit configured to detect a plurality of target devices; a controller configured to determine a plurality of resonance frequencies between a source resonator and the plurality of detected target devices; and a source resonance unit configured to transmit power of the determined plurality of resonance frequencies to the plurality of detected target devices, wherein the controller is further configured to: assign duty cycles to the plurality of detected target devices, each of the duty cycles corresponding to each of the plurality of detected target devices, control the source resonance unit to transmit the power to the plurality of detected target devices based on the duty cycles, and adjust an amount of the power by adjusting the duty cycles based on state information of thebplurality of detected target devices.
