Experimental Superconducting Transformer for Current Set Up

Journal of Applied Physics, 1971
For certain applications one would like to use relatively few turns of a high current conductor to make superconducting magnets. High current conductors introduce the problem of large heat leaks, and also the problem of a high current power supply. These problems would be simplified if one could make a suitable current step-up transformer.

Transformer Coupling and Its Modelling for the Flux-Ramp Modulation of rf-SQUIDs

Instruments, 2018
Microwave SQUID (Superconducting QUantum Interference Device) multiplexing is a suitable technique for reading a large number of detector channels, using only a few connecting lines. In the HOLMESexperiment, this is based on inductively coupled rf-SQUIDs

An ac biased superconducting flux transformer

Journal de Physique III, 1994
The coupled motion of the vortex lattices of two electrically insulated, superimposed, superconducting thin films (primary and secondary) in a perpendicular magnetic field, is predicted to exhibit a Josephson-like behavior. For a dc applied current flowing in the primary film, the voltage difference between the time-averaged primary and secondary flux ...

Comparison of the efficiency of superconducting and conventional transformers

Journal of Physics: Conference Series, 2010
For a transformer, the annual energy loss depends on the load-dependent efficiency of the transformer and the characteristic load curve at the specific location in the grid or elsewhere. The goal of this work is the comparison of the efficiency and the annual energy losses of a superconducting (from 2G high temperature superconductors) and conventional

Phase diagram from nonlinear interaction between superconducting order and density: toward data-based holographic superconductor

Journal of High Energy Physics
We address an inverse problem in modeling holographic superconductors. We focus our research on the critical temperature behavior depicted by experiments. We use a physics-informed neural network method to find a mass function M (F 2), which is necessary

Damping of inrush current in superconducting transformer

Przeglad Elektrotechniczny, 2014
In present study we analyze the inrush current in transformers with windings made of high-temperature superconducting materials. We analyze the phenomenon of damping the inrush current in superconducting transformers. Theoretical analysis results are compared with results of measurements of one-phase HTS 8,5 kVA transformer.
