1. A method for controlling a power electronics system for a vehicle, the method comprising:
- selecting one switching state of the power electronics system from a number of possible switching states of the power electronics system in dependence on at least one pre-determined requirement for spectral characteristics of an error signal of an output voltage of the power electronics system, while maintaining a current timing of a modulator of the power electronics system, andsetting the selected switching state in the power electronics system.

Abstract
Method for controlling a power electronics system for a vehicle in which, while maintaining a current timing of a modulator of the power electronics system, one switching state of the power electronics system from a number of possible switching states of the power electronics system is selected in dependence on at least one requirement, to be provided in advance, for spectral characteristics of an error signal of an output voltage of the power electronics system and is set in the power electronics system.

12. A modulator for a power electronics system, the modulator comprising:
at least one control device which is configured to select one switching state of the power electronics system from a number of simulated switching states in dependence on a comparison of at least one pre-determined requirement of spectral characteristics of an error signal of an output voltage of the power electronics system with respective frequency spectra of error signals of an output voltage of the power electronics system which, in each case, correspond to a simulated switching state of the power electronics system and to set the one switching state at the power electronics system with constant timing of respective switching rates of the power electronics system. - View Dependent Claims (13)
