METHOD AND DEVICE FOR CONTROLLING A MOTOR VEHICLE ALTERNOMETER, AND CORRESPONDING ALTERNOMETER

摘要

The method according to the invention is implemented in an alternator-starter (1) comprising phase windings (u, v, w) connected to an inverter (3) connected to an on-board electrical network (2) powered by a battery for starter operation. According to the invention, the inverter is commanded in a chopped full-wave control mode when the rotation speed (Ω) of the alternator-starter is lower than at least one threshold speed and in a full-wave control mode when the rotation speed is greater than the threshold speed. According to a particular embodiment, the switching between the chopped full wave control mode and the full wave control mode occurs according to a hysteresis cycle using two predetermined threshold speeds.
