Abstract
A method and a device for monitoring a plurality of parallel-connected semiconductor switches. The method includes subjecting the plurality of semiconductor switches to a heating pulse, in which a predefined load current flows for a predefined period of time in order to achieve a predefined temperature change of the semiconductor switches, a variable of a semiconductor switch to be monitored from the plurality of semiconductor switches being detected both before and after the application of the heating pulse, and a state of the semiconductor switch to be monitored and/or an electronics packaging, which corresponds to the semiconductor switch to be monitored, being ascertained on the basis of a deviation of the change of the at least one variable from a predefined reference value. The method enables a measurement of individual semiconductor switches to be monitored from the plurality of semiconductor switches.
