Abstract

An inverter has at least one current phase along a first axis and an input-side current connection for each phase, for receiving a DC input current. The phase(s) output AC output current generated from the DC input current, which is generated by a semiconductor bridge circuit. An intermediate circuit connected in parallel to the bridge circuit has at least one capacitor and heat sink between the intermediate circuit and the bridge circuit. The bridge circuit lies on the heat sink. The bridge circuit has at least one half bridge for each phase, formed by a high side switch and an opposing low side switch, connected in parallel, and each of the phases is located between the associated high and low side switches and on the heat sink, and each high and low side switch is electrically connected directly to the respective phase via a first electrical contact connection.
