Stromrichter-Module mit einem Verschienungssystem für Leistungshalbleiterschalter

摘要

The module includes power semiconducting switches and a rail provision system containing a positive connection (6), a negative (7) connection and a rail-shaped phase connection (8) which are stacked upon each other with intermediate isolation elements and attached to a base plate (5). The positive and negative connections are rail-shaped and have at least a first protruding strip (9,10) on a long side. Each phase connection has at least a second protruding strip (11) on one long side. The first and second strips interwork to hold and electrically contact the power semiconducting switches. Each two semiconducting switches are arranged in pairs on opposite long sides of the positive and negative phase connections with their front and rear sides facing each other.
