ABSTRACT:
A power semiconductor module comprising: a substrate, a plurality of conductor tracks arranged thereon, the conductor tracks being electrically insulated from one another, and including power semiconductor components arranged thereon; a connecting device, composed of an alternating layer sequence of at least two electrically conductive layers and at least one electrically insulating layer disposed therebetween, for the circuit-conforming connection of the power semiconductor components, the conductor tracks and/or external contact devices. The electrically conductive layers form connecting tracks and at least one transformer is formed integrally with, and thus from the constituent parts of, the connecting device. The transformer is composed of at least one transmitter coil and at least one receiver coil, which are in each case arranged coaxially with respect to one another and are formed with spiral windings.
