Abstract

A transformer for a DC-DC converter, such as a resonant converter, is provided. The converter includes a transformer unit that includes at least one winding with a first winding connection and a second winding connection, and a capacitor assembly consisting of at least one capacitor with a first capacitor assembly connection and a second capacitor assembly connection. The capacitor assembly is arranged so as to lie against the transformer unit in order to form an assembly. The capacitor assembly connections are connected to the winding connections via one or more first connection parts in a specified manner with respect to the electric connections. The capacitor assembly connections and/or the winding connections are electrically connected to multiple second connection parts in a specified manner with respect to the electric connections for connecting to a first power module and a second power module.
