rectifier bridge to polyphase generator and the polyphase alternator having such a bridge

The rectifier bridge for polyphase alternator having a polyphase armature coil consisting of phase outputs, of the type comprising a plurality of parallel in branches each comprising a pair of diodes (80, 100) connected in series and a connection point (114 ) intended to be connected to one of the phases of the outputs (23) of the armature coil, at least one of its branches comprising two diodes (80, 100) threshold voltage (Vf) less than 0, 7V , one of which (80), said first diode has a threshold voltage lower than the voltage threshold of the other diode (100), said second diode, and a leakage current greater than the leakage current of the first diode (80). The alternator is provided with at least such a bridge. Application: motor vehicle
