Pulsweitenmodulationsverfahren für in Serie geschaltete 2-Punkt-Umrichter

摘要

The converter system consists of series switched stages that are coupled between a power line take off contact Ä1Ü via an inductance Ä3Ü and a wheel Ä2Ü. Each of the stages is a two point converter ÄZPU1-NÜ and each stage has a pair of solid state switches ÄS1.1,S1.2Ü together with a switch ÄA1Ü operated with a phased activation signal.
