Effect of combining a DC bias current with an AC transport current on AC losses in a High Temperature Superconductor

, 1998
Creating complex flux configurations by superposing a dc current or magnetic field onto the ac current in a type II superconducting tape should lead to a variety of peculiar behaviors.

FOCUS-HTS: a new stellarator coil design code for three-dimensional high-temperature superconducting magnets

Nuclear Fusion
Stellarators mainly utilize magnetic fields from external coils to confine the plasma, enabling steady-state operation while avoiding instabilities like disruptions raised from plasma currents.

Modeling and simulation of termination resistances in superconducting cables

, 2016
We address the problem of modeling termination resistances which are largely responsible for the uneven distribution of currents in superconducting cables. For such purpose we present three DC models.

Study of Superconducting Fault Current Limiter Functionality in the Presence of Long-Duration Short Circuits

Energies
In this paper, superconducting fault current limiter (SFCL) operation in the presence of a long-duration fault is presented. The SFCL device utilizes second-generation high-temperature superconducting (2G HTS) tapes, which exhibit zero resistance under ...

Lightweight and Large-Current HTS Stacked Tape Conductor

IEEE Transactions on Applied Superconductivity
More electric aircraft (MEA) is one of the technical trends in the aviation field, and its merits are high safety, lightweight, easy to control, and good economy. Boeing 787 consumes almost ten times more electric power than conventional aircraft, so the power cable weight is ∼ ten times heavier than that of traditional aircraft. As a result, we need a

Self-consistent Modeling of the $I_c$ of HTS Devices: How Accurate do Models Really Need to Be?

, 2014
Numerical models for computing the effective critical current of devices made of HTS tapes require the knowledge of the Jc(B,theta) dependence, i.e. of the way the critical current density Jc depends on the magnetic flux density B and its orientation ...
