Analytical Calculation Of Electrical Characteristics Of Rectilinear Superconductors: Compound Excitation With Prevailing Action Of A Power Source

摘要

Based on formulas [1, 2], analytical expressions were obtained for the calculation of the electric characteristics of a superconductor excited by both the power source and a uniform external magnetic field. The latter is assumed to be proportional to the transport current, and the coefficient of proportionality has such a value that the currents in the saturated zone have the same direction throughout the entire cross section. The formulas obtained are analytically precise for a rectilinear superconductor with an elliptical cross-section shape. An example of the calculation of the sinusoidal transport current waveform is also given.
