A Control Method of Excitation Winding Magnetization for a Novel HTS Magnetic Flux Pump
The main purpose of magnetic flux pump is to stabilize magnetic field of superconducting magnets. This paper chiefly presents a kind of control method to magnetize excitation winding and control system design for a novel high temperature superconducting(HTS) magnetic flux pump. The basic structure and operation principle of the flux pump is simply described here. According to a stated magnetizing sequence of 7-pairs of magnetic poles, we use a singlechip to control the excitation winding to be magnetized one by one. The whole control system has been designed and developed, and the working performance has been tested. The experimental result shows that by this kind of control method, magnetic flux can be smoothly pumped into the HTS closed loop system, consequently compensate the magnetic field decay and make the HTS magnet operate in persistent current mode.
