Abstract
A method for protecting a controllable semiconductor switch from overload and short-circuiting in a load circuit, the method—including detecting an output voltage of the semiconductor switch;—comparing a detected output voltage with a predicted switching progress; and—deactivating the semiconductor switch if the detected output voltage is lower than the predicted switching progress.
