Beschreibung
Zusammenfassung:	The invention relates to a half bridge module in a traction inverter for a power electronics unit in an electric or hybrid vehicle, comprising a substrate, semiconductor switching elements on a first side of the substrate, power connections, to which power lines that conduct electrical traction energy are connected, signal connections, to which signal lines are connected for switching the semiconductor switching elements, and a casting compound, which encompasses the substrate and the semiconductor switching elements on the first side of the substrate, wherein the power connections and the signal connections are accessed from the first side of the substrate, such that the power connections and the signal connections extend through the casting compound, seen from the first side of the substrate, and are located within a base area spanning the substrate, seen from the direction they pass through the casting compound.
