METHOD FOR ACTUATING A SEMICONDUCTOR POWER SWITCH, ACTUATION CIRCUIT FOR A SEMICONDUCTOR POWER SWITCH, AND ELECTRONIC CIRCUIT BREAKER

A method for actuating a semiconductor power switch of an AC circuit is provided, which can be activated or deactivated by the semiconductor power switch. The method has the following steps: a) ascertaining the present current value and the present voltage value of the AC circuit; b) ascertaining whether the present current value exceeds a specifiable maximum value and if so, c1) generating an actuation signal for deactivating the current circuit, c2) generating an actuation signal for activating the current circuit within a period of time after generating the actuation signal for deactivating the current circuit, wherein the period of time is less than or equal to the period duration of the voltage, and c3) ascertaining whether the present current value exceeds a specifiable maximum value, which corresponds to the previous maximum value or is less than the previous maximum value, after activating the current circuit.
