For the miniaturisation of resonant converters the resonant inductor has been integrated into the transformer by using the leakage inductance as the inductor. A new method of adjusting the leakage inductance for planar transformers with integrated windings by using an additional layer of low permeable magnetic material is introduced. The leakage inductance of planar transformers with integrated windings can be adjusted very precisely and reproducibly.
