摘要： 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.

摘要： The invention relates to the controlling of a multi-phase rectifier for adapting the temperature distribution in the rectifier. According to the invention, the phase currents in the individual phases are adjusted on the output-side of the rectifier with a different amplitude. Correspondingly, the respective half bridges in the rectifier are loaded to a differing degree. In this way, an uneven temperature distribution can be compensated in the rectifier. Alternatively, an uneven temperature distribution can also be adjusted in the rectifier in a targeted manner, in order to take further parameters into account.

摘要： The present invention provides a method and a device for operating an electric machine for a soft changeover from a normal or free-wheel mode to an active short-circuit. To this end, a voltage with which the electric machine is actuated is first reduced in a defined manner to a predefined, preferably very low value and then the phase connections of the electric machine are short-circuited. Excessively high overcurrents, particularly overcurrents greater than the nominal current of the electric machine, can thus be avoided.
