Abstract
Wireless power transmitting and receiving apparatuses are described, using a superconducting coil for a resonant coil, and wireless power charging systems using the same. Wireless power charging systems described include a power source, a wireless power transmitter connected with the power source, a wireless power receiver, and a battery connected with the wireless power receiver. The wireless power transmitter includes a source coil connected with the power source, a superconducting transmitting coil into which electricity is induced by a magnetic field generated when electricity flows through the source coil, and a first conductive cooling device connected with the superconducting transmitting coil. The wireless power receiver includes a superconducting receiving coil that uses frequency resonance between the coils, a load coil into which electricity is induced by a magnetic field generated when electricity flows through the superconducting receiving coil, and a second conductive cooling device connected with the superconducting receiving coil.
