Abstract: The present disclosure relates to a transformer arrangement (1) for mounting in an electrical power unit of a vehicle. The arrangement (1) comprising a transformer core (2) and a thermal shell (3) in contact with said transformer core (2). The transformer core (2) comprises a plurality of winding portions (4) extending from a common centre portion (c1) of said core (2), along a first axis (x1), a second axis (x2) and a third axis, (x3) each axis (x1, x2, x3) being orthogonal relative to each of the other axis (x1, x2, x3). Furthermore, each winding portion (4) comprises a conductive coil arrangement (5) wound around each winding portion (4).
