  • Patent number: 10373784
    Abstract: A superconducting arcing induction type DC circuit breaker includes a superconducting fault current limiter and an arcing induction type DC circuit breaker connected in series to each other. The arcing induction type DC circuit breaker includes an induction member that has a through-hole, is continuously formed in a 360-degree direction, and has a certain shape and thickness, and an induction needle that protrudes from an inner surface of the induction member toward a center of the induction member. A contact point where an anode and a cathode, which are mechanical contacts, approach from opposite directions and come into contact with each other is formed in the through-hole of the induction member, and the anode and the cathode are separated in a direction far away from each other.

  • Publication number: 20160211064
    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.
