Beschreibung
Zusammenfassung:	The invention relates to a method for controlling a current converter, in particular a current converter having a plurality of sub-current converters connected in parallel, comprising the following steps: determining a desired voltage for the current converter; dividing the output voltage for the current converter into a plurality of, in particular identical, voltage ranges, wherein the voltage ranges are bounded by a discrete voltage upper limit and a discrete voltage lower limit; and the voltage range can be adjusted by switching the current converter, in particular a sub-current converter; associating a desired voltage with one of the voltage ranges having a discrete voltage upper limit and a discrete voltage lower limit; associating the first switch position with a lower voltage limit; associating the second switch position with a voltage upper limit; the current converter is switched between a first switching position and a second switching position such that the current converter produces an actual volt
