This paper investigates a hybrid winding concept for a toroidal inductor by simulating the winding resistance as a function of frequency. The problem of predicting the resistance of a non-uniform and complex winding shape is solved using 3D Finite Element Modeling. A prototype is built and tested experimentally to verify the simulation results. Finally, the COMSOL Multiphysics® LiveLink™ to AutoCAD® is utilized to highlight a bottleneck for this kind of winding scheme.
