Abstract

Es werden eine Vorrichtung und ein Verfahren zum Schalten eines induktiven Verbrauchers beschrieben. Ein erster Anschluß des Verbrauchers steht über ein erstes Schaltmittel mit Masse in Verbindung. Ein zweiter Anschluß des Verbrauchers steht mit einer Versorgungsspannung in Verbindung. Eine Induktivität ist über ein zweites Schaltmittel mit Masse verbindbar. Es sind Mittel vorgesehen sind, die die Schaltmittel derart ansteuern, daß die beim Unterbrechen des Stromflusses durch die Induktivität freiwerdende Energie zum Schalten des Verbrauchers verwendet wird.
