MICRO-HYBRID SYSTEM PROVIDED FOR POWERING AN ELECTRICAL DISTRIBUTION NETWORK OF A MOTOR VEHICLE.

摘要

The invention relates to a micro-hybrid system (1) for a motor vehicle comprising a rotating electrical machine (2), at least one power converter (3) adapted to be connected to an electrical distribution network (7) of the vehicle, network (7) comprising an energy storage unit (8), and a control circuit (4) adapted to control the power converter (3) to supply a supply current to the electrical distribution network (7). The system (1) comprises means (5) associated with the control circuit (4) for controlling, during a change of state between states of supply and non-supply of the supply current to the electrical distribution network ( 7), an at least partially progressive variation of a charging voltage delivered by the power converter (3) so as to obtain a corresponding variation of a mains voltage of the electrical distribution network (7) of a first value of mains voltage to a second network voltage value. A duration of said variation between said first and second network voltage values is determined so as to eliminate a negative effect of the change of state on the environment of the micro-hybrid system (1).
