Impacts of the Saturated Transformer on the HTS Flux Pump

Flux pumps have attracted increasing attention due to its capability of energizing superconducting coil wirelessly and avoid thick current leads which cost huge power loss. The transformer-rectifier flux pump is one type of the most important pumps, which is promising in real application. It usually made up of two main parts, the transformer and the dynamic bridge. This paper will investigate the impact of the saturated transformer on working performance of the flux pump. Based on the working principle of the flux pump and the transformer, analysis and comparison on how the saturation degree of the transformer on the flux pump will be carried out. Simulation tests based on Simulink software package will be carried out to verify all the analysis in the paper.
