Abstract
A device for triggering an electromagnetic load. The load is formed by at least two partial inductances. The load can be connected to the ground via a first switching device, and a partial inductance can be connected to the ground via a second switching device. The first switching device is triggered as a function of a voltage measured between the partial inductance and the second switching device.
Claims9
A device for triggering an electromagnetic load, the load being formed by at least two partial inductances, comprising:
- a first switching device for selectively coupling the load to a ground;
- a second switching device for selectively coupling at least one of the at least two partial inductances to the ground;
- and
- means for triggering the first switching device as a function of a voltage measured at a point between the at least one of the at least two partial inductances and the second switching device.

- a first switching device for selectively coupling the load to a ground;
- a second switching device for selectively coupling at least one of the at least two partial inductances to the ground;
- and
- means for triggering the first switching device as a function of a voltage measured at a point between the at least one of the at least two partial inductances and the second switching device, the means for triggering including a Zener diode coupled between the point and a control terminal of the first switching device.
