Abstract

A power module for an electric motor includes at least one semiconductor switch half bridge. The half bridge includes a high-side semiconductor switch and a low-side semiconductor switch. Each switch has a contact gap terminal formed by a surface region of the switch, in particular a flat surface region. The contact gap terminals, in particular a normal vector of the terminals, each points in a same direction. At least one electrically conductive layer is enclosed between the switches and electrically connects the contact gap terminal of the low-side semiconductor switch and the contact gap terminal of the high-side semiconductor switch of the half bridge to each other. Preferably an output terminal of the half bridge is formed by at least one electrically conductive layer.
