Current measuring system for switching devices arranged in a matrix configuration

Abstract

Some embodiments relate to a measuring system for determining currents through electric switching devices arranged in a matrix configuration and an arrangement, comprising these electric switching devices are disclosed. The measuring system and the arrangement comprise a plurality of current sensors each being associated with one of the switching devices. The current sensors neither surround said switching device nor any electric conductor leading to or from said switching device. Further on, the measuring system and the arrangement comprise a measuring unit, which is designed to receive raw measurement values from the current sensors and to calculate currents through the electric switching device. A current through an electric switching device is calculated based on the raw measurement value received from the current sensor associated with this switching device and based on the raw measurement value received from at least one other of the current sensors.
