A composite superconducting tape, a combination and preparation method thereof, and a defect bypassing or an end joint connection method. The composite superconducting tape includes a plurality of superconducting tapes, including a first superconducting tape and a second superconducting tape. The first superconducting tape includes a first superconducting layer, and the second superconducting tape includes a second superconducting layer. A side of the first superconducting tape close to the first superconducting layer is bonded with a side of the second superconducting tape close to the second superconducting layer along a length direction. The first superconducting tape is misaligned with the second superconducting tape along a width direction, such that the side of the first superconducting tape has a first vacant area for bonding with a second conductive tape, and the side of the second superconducting tape has a second vacant area for bonding with the first conductive tape.

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.
