The present disclosure provides a bidirectional LLC resonant converter and an integrated magnetic component for such a bidirectional LLC resonant converter. In order to increase the power density of such a converter, the I cores of the corresponding conventional converter are removed and the remaining windings (P1, S1, Lr1, Lr2) for the transformer and the series resonant chokes are arranged and connected such that the magnetic fluxes generated in the yokes of the transformer core elements (E3, E4) at least partially compensate each other. In another example, the windings and the core elements of the series resonant chokes are removed as well and the series resonant inductances are implemented by windings air gaps provided between the primary and the secondary windings wound on the transformer core elements.
