Abstract

The present invention relates to a variation of the clock frequency for pulse-width-modulated actuation of an electrical converter. In this context, the clock frequency can be specifically lowered in an angle range of an electrical period of an AC current to be output. The specific lowering of the clock frequency during predetermined angle ranges of the electrical period allows the load on the switching elements in the converter to be adjusted. As a result, it is possible, by way of example, to adjust the temperature distribution or thermal load in the converter.
