Abstract
A circuit arrangement, an electrical system, and a method for determining barrier layer temperatures of gate-controlled semiconductor components. First and second semiconductor components of the circuit arrangement are connected in parallel and activated using a gate control circuit which, in an active forward mode of the two semiconductor components, varies a first gate voltage of the first semiconductor component using a first signal, and to varies a second gate voltage of the second semiconductor component using a second signal that is opposite the first signal. An evaluation unit of the circuit arrangement is configured to use first and second current measuring devices to measure first and second gate currents of the first and second semiconductor components, respectively, and to determine in each case, based on the particular varied gate voltages and the respective corresponding gate currents, respective barrier layer temperatures of the two semiconductor component.
