摘要： A charging and field supplement circuit for superconducting magnets based on a pulsed current includes a capacitor charging circuit, an energy-storage capacitor, a capacitor discharging circuit, a superconducting magnetic energy storage circuit, and a superconducting persistent-current switch. Two output ends of the capacitor charging circuit are respectively connected to two ends of the energy-storage capacitor. Two input ends of the capacitor discharging circuit are respectively connected to the two ends of the energy-storage capacitor. Two output ends of the capacitor discharging circuit are respectively connected to two input ends of the superconducting magnetic energy storage circuit. Two output ends of the superconducting magnetic energy storage circuit are respectively connected to two input ends of the superconducting persistent-current switch. Two output ends of the superconducting persistent-current switch are configured to charge and magnetize a target superconducting magnet.
