Abstract

Transformer (100) comprising a core (10) extending along a winding axis (A). The transformer (100) further comprises a winding (20) wound around the core (10) and extending along the winding axis (A), wherein the winding (20) terminates in a first axial end surface (21) and in a second axial end surface (22). The first axial end surface (21) is arranged opposite the second axial end surface (22) along the winding axis (A). The first axial end surface (21) and the second axial end surface (22) extend along a radial direction (R), which is perpendicular to the winding axis (A). The transformer (100) further comprises a ring element (30) arranged at the first axial end surface (21). The ring element (30) comprises ferromagnetic sheets (31), aligned along the winding axis (A). The ring element (30) further comprises an insulating shell (32) covering the ferromagnetic sheets (31).
