Abstract

A control device for a power output stage is proposed, which includes a power output stage control which generates a triggering signal as a function of at least one control signal, for triggering at least one power output stage, which switches an electric load, preferably an inductive load having a recovery diode, a recording device being provided which records a measure for an electrical magnitude, which is applied to electric load. A feedback system is also provided, which supplies the power output stage control with at least one feedback signal as a function of the measure for the electrical magnitude, so as to influence the trigger signal.
