TL;DR: In this article, the propulsion force of a high-temperature superconducting (HTS) linearly synchronous driving motor (LSM) was estimated using the so-called T-A model.

TL;DR: In this paper, a contactless self-regulating high temperature superconducting (HTS) flux pump was proposed to charge the HTS magnet with all the conventional constituents outside the cryostat, and the operating frequency could be very low to evade inducing large eddy current as well as losses on the Cryostat wall.

TL;DR: In this paper, the authors investigated the frequency-dependent transport ac losses of two representative commercial coated superconductors (CCs) at tens of kilohertz band and established a circuit model to understand the underlying mechanism, and found that the current in metal components is not commonly thought eddy current, but a transport current driven by the power supply and surrounding magnetic fields.

TL;DR: In this paper, an analytical circuit topology design for wireless power transfer (WPT) coupler and a cryogenic rectifier is proposed for charging HTS magnet without electrical contact, which can get rid of current leads through ambient temperature to liquid nitrogen temperature.

TL;DR: In this article, the authors proposed the means of combining the current-controlled transformer-rectifier type flux pump with a secondary resistor to achieve an improved charging performance, which was confirmed that the proposed method is viable.
