Device for feeding electrical current in a three-phase network

摘要

The arrangement is designed so that the intermediate circuit (7) is divided in relation to the voltage and the middle point (7a) of the intermediate circuit (7) is earthed. The generator (3) is designed as a 6-phase synchronous generator and with a phase shift of 60 degrees. The generator (3) has a star configuration with a led out star point. The mains converter (8) in each current phase has two or more transistors (11) or thyristors, which are connected relative to the switch frequency; phase shifted about 180 degrees.
