Abstract

An electricity distribution network for a motor vehicle, the network having at least two pieces of equipment connected to a storage battery, at least one of the pieces of equipment operates in a pulse mode likely to create oscillations in the network at a resonant frequency thereof, the network includes at least one resistive element and capacitor that are associated in series and that are of resistance and capacitance determined so that the resistance of the resistive element is equal to a damping resistance for the network.

Claims

1. / An electricity distribution network for a motor vehicle, the network having at least two pieces of equipment connected to a storage battery, wherein at least one of the pieces of equipment operates in a pulse mode likely to create oscillations in the network at a resonant frequency thereof, and wherein the network includes at least one resistive element and capacitor that are associated in series and that are of resistance and capacitance determined so that the resistance of the resistive element is equal to a damping resistance for the network.

2. / A network according to claim 1, wherein the resistive element and the capacitor are connected between terminals for connecting the piece of equipment that operates in pulse mode to the network.

3. / A network according to claim 1, wherein the resistive element and the capacitor form a damping circuit located close to one end of the network.

4. / A network according to claim 3, including a plurality of damping circuits each adjacent to an end of the network.

5. / A network according to claim 1, wherein the pieces of equipment and the storage battery are interconnected by a bus having two ends, and wherein the network has at least one damping circuit adjacent to one of the ends of the bus.

6. / A network according to claim 5, having two damping circuits each adjacent to a respective end of the bus.
