Abstract: A forward converter comprises a magnetic component with a transformer and a filter output inductor. Also disclosed is a method for assembly of a forward converter. A first and a second U/UR core are arranged to form an O-core. Windings of the transformer are arranged on the O-core. A bobbin-less U/UR core is arranged to abut the O-core, and windings of a filter output inductor are arranged directly on a body section of the bobbin-less U/UR core. Alternatively, windings of the transformer are arranged on a first section of an E/ER core, and windings of the filter output inductor are arranged directly on a second, bobbin-less section of the E/ER core.

Abstract: A device for locking a unit (2) in a holder (1), having a first locking element (3), which has a first latching element (4) and is contained by the unit (2), and having a second locking element (5), which has a second latching element (5) and is contained by the holder (1), wherein at least one of the locking elements (3, 5) is mounted in a movable manner and can be subjected to force for the purpose of locking the two latching elements (4, 5), and wherein the locking device comprises a first stop (18), for limiting maximum deflection of the movable locking element (3), the locking device comprises a second stop (19), for limiting overlapping of the two latching elements (3, 5) in the locked state.
