Beschreibung
Zusammenfassung:	A method is disclosed for switching a semiconductor switch from a first static switch state to a second static switch state by controlling a control connection of the semiconductor switch. The method includes switching the semiconductor switch in a current-controlled manner starting from the first static switch state in a first switching phase by applying at least one first specified actuating current at the control connection of the semiconductor switch in a controlled manner, and switching the semiconductor switch in a voltage-controlled manner in a second switching phase following the first switching phase by applying at least one first specified actuating voltage to the control connection of the semiconductor switch in a controlled manner until the second static switch state is reached. In this manner, switching losses are reduced.
