Abstract
A control circuit for controlling a semiconductor component (,) comprising an emitter (E), a collector (C) and a gate (G), the control circuit comprising a gate driver (GD) the output of which is connected to the gate (G) of the semiconductor component to be controlled. The control circuit further comprises a resistance coupling (,) where two series connections of a diode (V,, V,) and a resistor (R,, R,) are in an antiparallel connection and connected between the emitter (E) of the semiconductor component (,) and the zero potential (Com) of the gate driver (GD), and a feedback capacitor (C,) connected between the collector (C) of the semiconductor component (,) and the end of the resistance coupling (,) connected to the zero potential (Com) of the gate driver.
