The eddy current losses in the matrix of twisted filament HTS tapes have been calculated using 3D commercially available finite element method (FEM) analysis tool of Ansoft Maxwell 3D®. At various reference points, numerical calculations were compared with analytical expressions to validate the numerical results. Numerical calculation of eddy current losses are plotted as a function of conductivity, frequency, transport current amplitude, and filament twist pitch in both rectangular and circular tape models. Circular model of same twist pitch and volume have lesser eddy current losses than rectangular tape model. Simulations results show that the eddy current losses are inversely proportional to the square of the filament twist pitch. Eddy current losses remain almost constant for the calculated frequency.
