Abstract

The invention relates to a method for operating a current converter, in particular of an electric machine, in which, for the or for each semiconductor switch of the current converter, a control signal (P') for setting a switch-off speed (A) is generated, wherein an electric intermediate circuit voltage (U) of an intermediate circuit is measured and compared to a voltage threshold value (U), wherein an operating temperature (T) of the respective semiconductor switch is measured and compared to a temperature threshold value (T), wherein a load current (I) switched by means of the respective semiconductor switch is measured and compared to a current threshold value (I), and wherein the control signal (P′) for setting the switch-off speed (A) is generated on the basis of the comparisons.
