Abstract :
AC losses of different kinds of available or anticipated HTS composite conductors were computed by using a magnetic diffusion model. The model takes into account the real current density-electric field characteristic of the superconductor and the spatial dependence of the current density, The computation was carried out for self-field losses due to transport current ramps and for magnetization losses in magnet operation due to ramping external magnetic field. Special attention was paid to filament coupling in various conductor models at different ramp rates.
