Abstract
A power electronics converter may include: a first multi-layer planar carrier substrate having one or more electrically conductive layers; a second multi-layer planar carrier substrate having one or more electrically conductive layers; a converter commutation cell circuit including a plurality of commutation cell components that are electrically connected together via the one or more electrically conductive layers of the first planar carrier substrate and electrical connections, the commutation cell components including one or more power semiconductor switching elements in one or more power semiconductor prepackages, each power semiconductor prepackage including a power semiconductor switching element embedded in a solid insulating material; one or more additional converter components electrically connected to the one or more electrically conductive layers of the second planar carrier substrate; and one or more further electrical connections connecting together one or more of the electrically conductive layers of the first carrier substrate and the second carrier substrate.
