Abstract
A device () for supplying electric current to the fuel pump () of a motor vehicle internal combustion engine () comprises a DC/DC converter () which increases voltage to a predetermined value in the event of a voltage drop of a direct current source (). This ensures an adequate voltage supply of the fuel pump () even at low voltages of the direct voltage source. When the voltage () of the direct voltage source () is sufficient, the DC/DC converter () is bridged, so that the fuel pump () is directly supplied with fuel from the direct voltage source (). The DC/DC converter is also bridged when the device is faulty.
