Abstract: An exemplary arrangement and method for a power semiconductor switch, where a first current between a first electrode and a second electrode can be controlled based on a control voltage between a third electrode and the first electrode. The arrangement includes an inductance connected in series with the power semiconductor switch, wherein a first end of the inductance is connected to the first electrode, first measuring source for generating a first measurement voltage based on the first end's voltage with respect to a reference potential, second measuring source for generating a second measurement voltage on the basis of the inductance's second end voltage with respect to the reference potential, a comparator for comparing the first measurement voltage with the second measurement voltage, and driver for generating the control voltage. The driver being configured to generate a first control voltage level and a second voltage level of the control voltage.
