Patent ID: 10505360

Abstract:
Determining a load current (IL) in a semiconductor switch, which has a measuring device, wherein a measurement of the load current (IL) is influenced by a transmission factor (k), depending on the measuring device, wherein the following steps are carried out: (a) execution of a first measurement of the load current (IL) with a first transmission factor (k1), wherein a first measurement result is determined with the first measurement; (b) execution of a second measurement of the load current (IL) with a second transmission factor (k2), wherein a second measurement result is determined with the second measurement, and the first transmission factor (k1) differs from the second transmission factor (k2), in order to identify an error (IF) in the measurement results; and (c) determination of a corrected measurement result through a comparison of the first measurement result with the second measurement result, such that the error (IF) is at least reduced.
