Abstract
A magneto-optical sensor monitors a semiconductor element in a semiconductor module. The magneto-optical sensor is arranged in a region of the semiconductor element or of at least one of the feed lines of the semiconductor module that make contact with the semiconductor element. A polarized light signal is reflected from the magneto-optical sensor or transmitted through the magneto-optical sensor. A current is determined from a polarization of the reflected or transmitted light signal.
