用于确定负载电流的方法和设备
摘要：
用于在半导体开关(20)中利用测量装置(21)确定负载电流(IL)的方法(100)，其中，负载电流(IL)的测量被与测量装置(21)有关的传输系数(k)所影响，其中实施如下步骤：a)以第一传输系数(k1)执行负载电流(IL)的第一测量，其中利用第一测量确定第一测量结果；b)以第二传输系数(k2)执行负载电流(IL)的第二测量，其中，利用第二测量确定第二测量结果，并且第一传输系数(k1)有别于第二传输系数(k2)，以便识别测量结果中的误差(IF)；c)通过比较第一测量结果与第二测量结果确定校正的测量结果，如此使得至少减小误差(IF)。
摘要（英）：

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.
