摘要
A current switching arrangement, in particular a converter or similar device, for controlled switching of an electric current from an input region to an output region, has at least one field-controlled semiconductor switching device (IGBT) (10) and an associated protection device (5), which in the event of a short-circuit in the current input region (3) switches an additional controlled input impedance (R1) to the semiconductor switching device (IGBT) (10), the latter then being switched off.
