Abstract

A device with power semiconductor components controlling the power of high currents has each power semiconductor component insulated and fixed to a common cooled carrier body. Conductor bars, in addition to the power semiconductor components, are fixed to the carrier body, the conductor bars being electrically insulated and placed on top of each other, whereby each semiconductor bar has a free contact surface, and one electrical contact surface of each semiconductor component is electrically connected to a conductor bar by one or several electric conductor bridges and another electrical contact surface of the power semiconductor component is electrically connected to another bar conductor by one or several conductor bridges.
