Abstract
A method for operating a multilevel converter in flycap topology, in which the multilevel converter has at least two semiconductor switches controlled by control pulses of variable pulse durations within a control period that recurs at a control frequency to selectively interconnect a voltage source connected to an input of the multilevel converter, an output of the multilevel converter, and at least one auxiliary capacitor arranged between the input and the output, for generating an output voltage. The method includes using at least one oscillation parameter that describes the oscillation behavior of at least one harmonic of an electrical measured variable, at least one correction pulse duration is determined for a future control pulse to reduce the amplitude of the at least one harmonic and at least one semiconductor switch is controlled with a control pulse of the determined correction pulse duration.
