CONVERTER IN DELTA CONFIGURATION

摘要

The invention relates among other things to a converter (10) for a three phase voltage with three electrically delta connected series circuits (R1 R2 R3) each comprising at least two switching modules (SM) connected in series and with a control device (30) connected to the switching modules (SM) that can drive the switching modules (SM) in such a way that branch currents with the fundamental frequency of the three phase voltage and with at least one additional current harmonic flow in the series circuits (R1 R2 R3) the additional current harmonic being dimensioned such that it flows in the series circuits (R1 R2 R3) of the converter (10) and remains inside the converter.
