Abstract

A power module is suggested having a simple and cost-effective arrangement and ensuring a reliable operation. To this end, a circuit arrangement comprising at least one electronic component is arranged on a carrier body. A conductor pattern is formed on the top side of the carrier body, and a structured cooling element made of the material of the carrier body, is provided on the bottom side. The invention also relates to a power module as power converter for electric motors.
