Abstract: A vehicle transformer has a transformer core with two opposed yokes and at least two limbs extending in between them along a parallel limb axis, wherein a support structure is provided at each of the yokes for carrying the vehicle transformer with horizontal oriented limb axis, wherein a hollow cylindrical coil with at least one respective electrical winding is arranged around at least one of the limbs. The coil may be rigidly connected with the limb so that the flexural resistance of the rigid combination of both is improved therewith compared to a combination of both without rigid connection.

Abstract: A transformer includes: two coils, each coil having a core and a plurality of windings; and a support device in which the coils are held, the support device having feet for setting up the support device on a base. Longitudinal axes of the coils can be oriented horizontally by setting up the support device on the base.
