A method for controlling a power converter, which in particular has partial power converters connected in parallel, is provided. The method includes determining a nominal voltage for the power converter; and dividing an output voltage for the power converter into a number of, in particular equal, voltage ranges. The voltage ranges are limited by a discrete upper voltage limit and a discrete lower voltage limit and the voltage ranges can be adjusted by switching the power converter, in particular the partial power converters. The method includes allocating the nominal voltage a voltage range with a discrete upper and lower voltage limits; allocating a first switch setting to the lower voltage limit; allocating a second switch setting to the upper voltage limit; and switching between the first switch setting and the second switch setting so that the power converter generates an actual voltage corresponding to the nominal voltage.
