  • Method and device for switching an inductor
    Patent number: 6140717
    Abstract: A method and device for switching an inductor are described. A first terminal of the inductor may be connected to ground via a first switching device. A second terminal of the inductor is always connected to a voltage power supply. A second inductor may be connected to ground via a second switching device. The energy released in the second inductor when the current flow is interrupted is used to switch the first inductor.

  • Device for triggering an electromagnetic load
    Patent number: 6040721
    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.

  • Method and device for driving a load
    Patent number: 5955792
    Abstract: A method and a device for driving a load, particularly an electromagnetic load. The current flowing through the load is detected, and is controlled by a control device connected in series to the load. During a first phase, in addition to the control device, a first switching device is driven that is disposed parallel to the control device. During a third phase, in addition to the control device, a second switching device is driven that is disposed parallel to the control device.
