AC/DCconverter and a control method thereof for charging electrical vehicles

The present disclosure refers to an AC/DC converter for an OBC. The AC/DC converter comprises: a three-phase-input comprising three inputs (a, b, c); a single-stage dual-active bridge, DAB, circuit; and an auxiliary circuit. The auxiliary circuit comprises two switching means (R1, R2) and energy storage means (C1), wherein the auxiliary circuit comprises at least two branches, wherein two branches each comprise one of the switching means (R1, R2), wherein at least one branch is connected to an input (a, b) which is a single-phase AC input, wherein another branch is connected to an input (c) which is not a single-phase AC input, and wherein the other branch comprises the energy storage means (C1).
