Abstract

A device for controlling at least one electromagnetic load, which includes a first switching device arranged between a first terminal of a supply voltage and a first terminal of at least one load, and a second switching device arranged between a first terminal of an assigned load and the second terminal of the supply voltage. The energy released during the transition from a first higher current (IH) to a second lower current (IH) is stored in a storage device.
