Abstract—Alternating current (ac) losses in high-temperature cryogenic stability and efficiency. We therefore need to evaluate
superconductor tapes and devices with transport current are the ac loss of the device accurately and then try every means to
solved by using the resistivity-adaption algorithm (RAA). The reduce the ac loss at the design stage. Accurate measurement
most advanced feature of the RAA is that it enables the simulation
of any model derived from the flux motion theory on finite-element of the ac loss of HTS devices by using the electric method is
analysis (FEA) packages that have an eddy current solver. The generally faced with two challenges. First, the inductive voltage
principle of the RAA, as well as its realization on the ANSYS FEA of HTS devices, particularly those with a large number of turns
package, is introduced. The simulation begins with the calculation and with ic circuits will inevitably be added into
of the ac loss of an ellipse and of strips with aspect ratios ranging loss signal. Second, HTS devices operated under plex
from 50 to 2000. The accuracy and efficiency of the calculation are
verified
