Description

Flux pumps are capable of injecting flux into an HTS circuit without electrical contact. They are ideal alternatives to traditional current sources and current leads to power HTS magnets. These devices make it possible for HTS magnets to be smaller, lighter, and more accessible.
    In recent years, our group in Cambridge has developed a transformer-rectifier HTS flux pump switched by dynamic resistance, which demonstrates superior performance. Despite the achievements, many works could be done to improve performance. This paper aims to analyze the power loss and efficiency of the flux pump and further reduce the loss. The analytical solution will be proposed and verified by comprehensive experiments.
