Abstract
A substrate and a first circuit board each have an upper side and a lower side. The substrate lower side is connected to a cooling body. On the upper side of the substrate, first electronic switching elements connect an alternating current potential at a phase terminal to a high direct current potential at a first potential terminal and to a low direct current potential at a second potential terminal. Second electronic switching elements connect the alternating current potential to a middle direct current potential at a third potential terminal. The substrate is spaced from the first circuit board under the first circuit board lower side. The upper side of the substrate faces toward the first circuit board. The second switching elements are at least on the upper side of the first circuit board, possibly additionally also on the lower side of the first circuit board.
