Abstract
This specification provides a wireless power system capable of changing a resonant frequency and a resonant frequency changing method thereof. To this end, a wireless power receiver according to one exemplary embodiment includes a power receiving unit having a receiving side resonant circuit provided with at least one inductor and at least one capacitor, and configured to receive a wireless power signal, the wireless power signal being generated based on a resonance phenomenon between the receiving side resonant circuit and a transmitting side resonant circuit of a wireless power transmitter, and a power reception control unit configured to control the power receiving unit to change a connection between the at least one inductor and the at least one capacitor so as to change a resonant frequency corresponding to the wireless power signal.
