Abstract :
Based on a theoretical analysis, the main components of a full-wave superconducting rectifier-type flux-pump, including a low-loss superconducting transformer with high coupling coefficient, superconducting thermally activated switches, protection system, control system and variable frequency and amplitude power supply, are developed. With the developed components, two flux-pump systems have been assembled and studied experimentally with different input current waves of various frequency and amplitude. Quite good results have been achieved. It can energize the superconducting magnet with different charging rate. The highest rectifier frequency is 0.35 Hz and the charging rate is 86.7 A/min with an efficiency of 96%. The paper summarizes the design, development and experimental results of the system
