Abstract

High temperature superconductor (HTS) is becoming more and more attractive for high field magnets. To charge the HTS magnets and operate them in persistent current mode, a persistent current switch (PCS) is necessary. This paper will focus on how to build a fast persistent current switch which can present a large resistance and with short recovery time. Impacting factors and strategy to control the PCS are discussed. An experimental system is built and tests are carried out to verify the practicality of the proposed PCS.
