INVESTIGATION OF CURRENT DENSITY, MAGNETIC FLUX DENSITY, AND OHMIC LOSSES FOR SINGLE-VEINED, LITZ AND FOIL STRUCTURED CONDUCTORS AT DIFFERENT FREQUENCIES

Today, although medium and high frequencies have been provided a significant reduction in the size of machine, it is known that as the more frequency increases, the higher losses at conductors. in this study, wire losses of the same cross section but different structures are examined by finite elements method. also, depending on the exchange rate in wires at conductors, changes of current density, magnetic flux density and ohmic losses were investigated. the use of different structured wires of conductors at different frequencies has been compared in terms of their losses, and given the graphics regarding to the design by special design software.
