N2 - A conduction-cooled HTS flux pump is a wireless DC power supply device for conduction-cooled superconducting magnets that compensates current decay and ensures magnetic field stability by pumping flux into the closed-loop circuit of superconducting magnets using the principle of electromagnetic induction. The majority of previous flux pumps worked under liquid nitrogen cooling, whose research focused on pumping efficiency and impact factors, rather than on applications in practice. Meeting the needs of practical applications in conduction-cooled HTS magnets, novel type conduction-cooled flux pump can significantly reduce the cost of HTS magnet power supply and operating energy consumption, and is of great significance for technological innovation of future HTS magnets used in offshore wind turbine, biomedical, high-energy physics, etc. This paper introduces the working principle and research progress of conduction-cooled HTS flux pump in recent years, reviews their different types proposed in the past. Finally, parameters of the conduction-cooled HTS flux pump in the future practical engineering are prospected, such as increasing working power, reducing heat loss, enhancing anti-electromagnetic interference ability and stability, controlling current accurately and optimizing data acquisition system etc.
