Title:
PULSE CHARGING AND MAGNETIZATION CIRCUIT FOR SUPERCONDUCTING MAGNET
Document Type and Number:
WIPO Patent Application WO/2022/088922
Kind Code:
A1
Abstract:
The present disclosure provides a pulse charging and magnetization circuit for a superconducting magnet, comprising a capacitor charging circuit portion (104), an energy storage capacitor C0, a capacitor discharging circuit portion (105), a superconducting magnetic energy storage circuit portion (106) and a superconducting constant current switch portion (107). Two output ends of the capacitor charging circuit portion (104) are respectively connected to two ends of the energy storage capacitor. Two input ends of the capacitor discharging circuit portion (105) are respectively connected to the two ends of the energy storage capacitor. Two output ends of the capacitor discharging circuit portion (105) are respectively connected to two input ends of the superconducting magnetic energy storage circuit portion (106). Two output ends of the superconducting magnetic energy storage circuit portion (106) are respectively connected to two input ends of the superconducting constant current switch portion (107). Two output ends of the superconducting constant current switch portion (107) charge and magnetize a target superconducting magnet. According to the present disclosure, the size of the charging device and the cross-section of a current lead are significantly reduced.
