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.

Figure 00000001
An apparatus and a method for switching an inductive consumer are described. A first connection of the consumer is connected to ground via a first switching means. A second connection of the consumer is connected to a supply voltage. An inductor can be connected to ground via a second switching means. Means are provided which control the switching means in such a way that the energy released when the current flow is interrupted by the inductance is used to switch the consumer.
