Abstract
Described is a micro-hybrid system for an automobile including: 1) a rotating electrical machine (i.e., a starter/alternator); 2) at least one power converter connectable to an electricity distribution network of the automobile, this network including a power storage unit; and, 3) a control circuit capable of controlling the power converter to provide a power supply current to the electricity distribution network. The system additionally provides a device associated with the control circuit for controlling, during a change of state between the states of providing and not providing the power supply current to the electricity distribution network, an at least partially gradual variation in a charge voltage generated by the power converter so as to obtain a corresponding gradual variation in a network voltage of the electricity distribution network from a first network voltage value to a second network voltage value, a duration of the variation between the first and second network voltage values being predetermined so as to eliminate a negative effect or consequences (surges, dimming of lights, etc.) of a state change on the electronic environment of the micro-hybrid system.
