SYSTEM FOR STABILIZING A SUPPLY VOLTAGE OF AN ONBOARD ELECTRICAL NETWORK OF AN AUTOMOTIVE VEHICLE

摘要

The invention relates to a system (1) for stabilizing a supply voltage (Ubat) of an onboard electrical network (2) of an automotive vehicle, of the type of those limiting a variation of voltage of a battery (3) supplying said network (2) at the moment of activation of an item of electrical equipment of said vehicle (4) linked to said network (2), characterized in that it comprises:- a variable resistor (6) varying as a function of said variation of voltage connected in series with said battery (3) and said item of equipment (4), said variable resistor (6) being controlled by a main current loop (7) as a function of a reference intensity (lref) generated by a voltage loop (8) as a function of said variation of voltage with respect to a reference voltage (Uref); - a constant resistor (20) in parallel with said variable resistor.
