Abstract

A clamping assembly includes a configuration of mechanically clamped components disposed one on top of the other to form a stack. A clamping device generates a mechanical compressive force on the configuration of the components and a pressure element transmits the mechanical compressive force from the clamping device to the configuration. The pressure element contains a metal foam for a planar, homogeneous transmission of the compressive force. A sub module of a converter having at least one series circuit of power semiconductor switching units implemented as the clamping apparatus is also provided.
