A simple model for the estimation of hysteresis energy loss in a coated conductor under the simultaneous application of a magnetic field and current

A simple model for estimating the hysteresis energy loss of coated conductors under a general load line was studied. We took advantage of the characteristic line Ib(Ha) to determine the major parameters used in this model. The value of Ib(Ha) was based on the scanning Hall probe measurements (SHP) o...

Description
Summary:A simple model for estimating the hysteresis energy loss of coated conductors under a general load line was studied. We took advantage of the characteristic line Ib(Ha) to determine the major parameters used in this model. The value of Ib(Ha) was based on the scanning Hall probe measurements (SHP) on a Sm1Ba2Cu3O7 - Delta *d coated conductor. During SHP measurement, a magnetic field (Ha) and current (Ia) were applied simultaneously and were varied along 11 different load lines. From the values of SHP measurements, the current density profiles, J(x, Ha, Ia), were calculated using a numerical inversion method. We define the quantity Ib = {integral} - ww
