Abstract

Es werden ein Verfahren und eine Vorrichtung zum Schalten einer Induktivität beschrieben. Ein erster Anschluß der Induktivität ist über ein erstes Schaltmittel mit Masse verbindbar. Ein zweiter Anschluß der Induktivität stet mit einer Versorgungsspannung in Verbindung. Eine zweite Induktivität ist über ein zweites Schaltmittel mit Masse verbindbar. Die beim Unterbrechen des Stromflußes in der zweiten Induktivität frei werdende Energie wird zum Schalten der ersten Induktivität verwendet.

Figure 00000001
A method and a device for switching an inductor are described. A first connection of the inductance can be connected to ground via a first switching means. A second connection of the inductor is connected to a supply voltage. A second inductance can be connected to ground via a second switching means. The energy released when the current flow is interrupted in the second inductor is used to switch the first inductor.
