  • Hybrid superconducting magnetic device
    Patent number: 10867731
    Abstract: A hybrid superconductive device for stabilizing an electric grid comprises (a) a magnetic core arrangement at least partially carrying an AC winding the AC winding connectable to an AC circuit for a current to be limited in the event of a fault; (b) at least one superconductive coil configured for storing electromagnetic energy; the superconductive coil magnetically coupled with the core arrangement and saturating the magnetic core arrangement during use. The hybrid superconductive device further comprises a switch unit preprogrammed for switching electric current patterns corresponding to the following modes: at least partially charging the superconductive coil; a standby mode when the superconductive coil is looped back; and at least partially discharging the superconductive coil into the circuit. Optionally, hybrid superconductive device comprises at least one passage located within said magnetic flux. The passage conducts a material flow comprising components magnetically separable by said magnetic flux.
