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.
