Transformer for a dc/dc voltage converter

[0031]In the present description, same elements are provided with same reference signs.

[0032]A transformer configured according to an embodiment, as shown schematically by way of example in a perspective illustration in FIG. 2, is used, for example, in a series resonant converter, as shown in FIG. 1. The transformer 30 according to one or more of the present embodiments includes a transformer unit 35 that includes the primary coil 31 already described in the introduction. The transformer unit 35, in addition to the primary winding 31, includes the secondary winding 32 and a stray inductance 33 that occurs during operation. It is therefore assumed in the following description that the stray inductance 33 is a component of the primary winding 31.

[0033]The transformer unit 35 is arranged in a housing 350 that has a substantially cuboid structure, merely by way of example. For the further description of the present embodiments, only the connection of the primary winding 31 to the first bri
