Claim Text:
1. A circuit for voltage stabilization of an on-board motor vehicle electrical system, the circuit comprising: a diode element comprising a plurality of first semi-conductor switches connected in parallel, wherein the diode element is configured and arranged to allow current flow only in a direction from an energy storage towards the on-board motor vehicle electrical system; a pilot and control circuit configured to determine an intensity of a current flowing through the diode element and to control said plurality of first semi-conductor switches of the diode element based on the determined current intensity in such manner that said plurality of first semi-conductor switches allow a current flow from the energy storage to the on-board motor vehicle electrical system, but block a current flow from the on-board motor vehicle electrical system to the energy storage; a battery electrically connected to the diode element and connectable to the on-board motor vehicle electrical system; and a switching unit connecting the battery to the on-board motor vehicle electrical system, the switching unit including: wherein the circuit is electrically connected between the on-board motor vehicle electrical system and the energy storage and wherein the circuit is electrically connected between the onboard motor vehicle electrical system and a starter, the circuit being adapted to stabilize the onboard motor vehicle electrical system.
