Abstract
The invention relates to a control device for a reversible, multi-phased rotating electrical machine which can operate in alternator or motor mode. The inventive device comprises a main battery (), an electric network () and a unit () for controlling and commanding an inverter and a rectifier bridge (P) for selection in alternator mode or starter mode. According to the invention, the machine is powered by the inverter which is connected to a start-up control unit which can provide a voltage greater than that provided by the main battery () over the network (). The inverter is connected to the positive terminal of the secondary voltage source via a first switch (K) in motor mode, while the rectifier bridge (P) is connected to the positive terminal of the main battery via a second switch (K) in alternator mode.
