Abstract
An optimization routine is presented to optimize a hybrid winding geometry for a toroid inductor in terms of the DC resistance. The hybrid winding geometry consist of bended foil pieces connected through traces in a printed circuit board. MATLAB is used to create a graphical user interface that visually plots the
winding using input parameters such as core dimensions, number of turns, clearance between windings, and the winding angle of each segment of the winding. COMSOL LiveLink is used to import the winding geometry from MATLAB and create a 2D finite element model to simulate the DC reisistance. Finally the winding configuration with the lowest DC resistance is found by sweeping the parameters of the winding geometry and simulate and save the result in each step. An improvement of more than 30% compared to previous work where achieved in this way
