Abstract
A method for controlling an electric amplifier is provided. The method includes monitoring a closed-loop control signal of a regulator, which triggers an end stage of the amplifier; adjusting the closed-loop control signal as a function of an output signal of the end stage; comparing the closed-loop control signal with a reference signal; triggering the end stage when an amplitude limit value and a period length limit value are exceeded or undershot by the amplitude value and period length value, respectively, of the closed-loop control signal; and blocking an input side and/or the regulator when the end stage is triggered.
