Converter modules having a busbar system for power semiconductor switches
First Claim
1. A converter module having power semiconductor switches (1) and a busbar system, comprising a positive connection (6), and negative connection (7) and a phase connection (8, 14, 15) which is in the form of a busbar, which connections are stacked one on top of the other with the interposition of insulating elements and are mounted on a baseplate (5), whereina) the positive connection (6) and the negative connection (7) are in the form of busbars and have at least one first projecting lug (9, 10) on one longitudinal side,b) each phase connection (8, 14, 15) has at least one second projecting lug (11, 17, 18) on its longitudinal side,c) the first and the second lugs interact in order to hold and make electrical contact with the power semiconductor switch, andd) in each case two power semiconductor switches are arranged in pairs on opposite longitudinal sides of the positive/negative/phase connections, with their front or rear sides facing one another.

Abstract
Converter modules have a busbar system for a plurality of power semiconductor switches or, preferably, IGBT power semiconductor modules (IPMs). The power semiconductor switches are arranged in pairs, facing one another or facing away from one another, close together and parallel. In accordance with exemplary embodiments, alternating current is fed in one or two phases via bridge circuits composed of two or four power semiconductor switches.
