Description

technical field [0001] The invention belongs to the high-temperature superconducting technical field, and in particular relates to a high-temperature superconducting coil excitation device. Background technique [0002] A high-temperature superconducting coil refers to a coil made of a second-type superconductor with a high transition temperature and a high critical magnetic field at a low temperature. Its main feature is that it has no resistance loss, can generate high magnetic field, and has strong practical value. [0003] At present, there are two excitation methods for high-temperature superconducting coils: one is to directly use DC power to supply power to high-temperature superconducting coils through current leads, but using DC power to supply power to high-temperature superconducting coils for a long time will cause two problems: On the one hand, the high-temperature superconducting coil DC power supply equipment is expensive and consumes a lot of energy; on the ...
