Abstract :
By introducing twisted coordinates, a quasi three-dimensional formulation is performed to evaluate A.C. losses such as hysteresis and coupling losses in type-II superconductors when both transport currents and magnetic field parallel to the currents exist. The numerical results indicate, that the hysteresis loss induced in the superconductors increases when the transport current exists, while the coupling loss is not affected by its existence
