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.
