Interleaving techniques in magnetic components

This work presents a study of the quantification of the benefits that can be achieved by applying interleaving techniques between different layers (interlayer effect) and in the same layer (intralayer effect). A method to estimate the leakage inductance is also introduced in this work. This method allows the designer to quantify the improvements that can be obtained applying interleaving techniques in an easy way using a simple calculation. Some design guidelines are extracted in order to select the best winding strategy for each transformer. The analysis has been carried out by means of finite element analysis (FEA) techniques in order to take into account all the frequency and geometry effects
