Abstract (en)
According to the present disclosure a transformer assembly is provided which comprises a core having a yoke. The yoke comprises a plane surface portion and an edge portion (8), wherein the edge portion (8) protrudes beyond the plane surface portion into a direction defined by a surface normal (N) perpendicular to the plane surface portion. Further, the transformer comprises a clamping plate (10) for clamping the yoke in a direction perpendicular to the surface normal (N), wherein the clamping plate (10) comprises a plane portion (12) oriented parallel to the plane surface portion of the yoke. The plane portion (12) of the clamping plate (10) is shaped such that the edge portion (8) of the yoke lies outside a projection of the plane portion (12) of the clamping plate (10) along the surface normal (N). In this manner, it is possible to reduce a distance between the plane portion (12) of the clamping plate (109 and the plane surface portion of the yoke. This allows reducing the extension of insulation members measured parallel to the surface normal which may be disposed between the plane portion (12) of the clamping plate (10) and the plane surface portion of the yoke.
