Claim Text:
1. A method for switching a semiconductor switch from a first steady-state switching state to a second steady-state switching state by controlling a control connection of the semiconductor switch the method comprising: in a first switching stage, applying, in a controlled manner, at least one first, predetermined actuation current at the control connection of the semiconductor switch to provide current-controlled switching of the semiconductor switch starting from the first steady-state switching state in a first switching phase, and in a second switching phase following the first switching phase, applying, in a controlled manner, at least one first, predetermined actuation voltage at the control connection of the semiconductor switch to provide voltage-controlled switching of the semiconductor switch until the second steady-state switching state has been reached either (a) the first steady-state switching state is an open switching state of the semiconductor switch, and the second steady-state switching state is a closed switching state of the semiconductor switch, or (b) the first steady-state switching state is a closed switching state of the semiconductor switch and the second steady-state switching state is an open switching state of the semiconductor switch, and the semiconductor switch is on in the closed switching state, and the semiconductor switch is off in the open switching state.
