High frequency resistance in flyback type transformers

Interleaving techniques are usually applied to magnetic components in order to reduce the leakage inductance and resistance. However, since the behavior of flyback-type transformers is different than conventional ones, the features of these techniques in these transformers are also different. This work presents a study of the modification of the resistance in flyback-type transformers when interleaving techniques are applied, as well as the main differences compared with its application in conventional transformers. The results have been quantified using FEA techniques in order to account for geometry and frequency effects
