Abstract

Es wird ein Verfahren zum Schalten einer induktiven Last (2) vorgeschlagen, das ein schnelles Schalten dieser Last ermöglicht. Dazu ist vorgesehen, dass eine der Last aufschaltbare Schaltspannung sprungförmig auf eine vorgebbare Maximalspannung (Um) wechselt und dass nach dem Erkennen einer Laststromschulter (Ss) oder nach Ablauf eines vorgebbaren Zeitintervalls die Maximalspannung (Um) auf eine Haltespannung (Uh) sprungförmig oder getaktet reduziert wird.

A method for switching an inductive load (2) is proposed which enables this load to be switched quickly. For this purpose, it is provided that a switching voltage that can be applied to the load changes abruptly to a predeterminable maximum voltage (Um) and that after the detection of a load current shoulder (Ss) or after a predefinable time interval, the maximum voltage (Um) is suddenly or clocked reduced to a holding voltage (Uh) becomes.
