Abstract
A method for setting a reference potential of a current sensor in a power semiconductor device is disclosed. On the basis of a specific geometry and a typical two-dimensional potential distribution of the power semiconductor device, a plurality of tapping points is predetermined on an area of the power semiconductor device. On the basis of the specific geometry of the power semiconductor device, a line course between the tapping points and a measuring point for measuring a potential average value is determined and realized. Respective potential values are detected at the tapping points and fed to the measuring point. The potential average value is determined at the measuring point. The potential of the current sensor is set to the potential average value thus determined.
