摘要

1/1 Summary "Converter for a Three-Phase Voltage, and Method for Operating a Converter for a Three-Phase Voltage" The invention relates, among other things, to a converter (10) to three-phase voltage with three series delta electrically connected circuits (r1, r2, r3), each comprising at least two serially connected switching modules (sm) , and with a control device (30) connected to the switching modules (sm) that can drive the switching modules (sm) in such a way that currents derived with the fundamental frequency of the three-phase voltage And with at least one additional harmonic current flowing in the series circuits (r1, r2, r3), the additional harmonic current being scaled such that it flows into the series circuits (r1, r2, r3) of the converter (10) and remain inside the converter.
