Abstract

A power converter having at least two semiconductor substrates is provided. Each of the substrates has at least two contact surfaces, and the converter also has two thermally conductive mounting plates carrying the semiconductor substrates, which each have an electrical terminal, an attachment arrangement implemented on one of the mounting plates, and having at least one third electrical terminal, which is distinguished in that the mounting plates and the semiconductor substrates form stacks, the mounting plates receiving the semiconductor substrates between themselves, and an electrically and thermally conductive insert, which has at least the third terminal, is arranged between the semiconductor substrates.
