Embodiment Construction
[0037] exist figure 1 A device with generators 20 , 30 , bridge rectifier 40 and control device 50 is schematically shown in FIG. 3 using the example of a three-phase system. The described arrangement is part of the on-board electrical system 10 of the motor vehicle, which is only partially shown here.
[0038]The generator 20, 30 comprises a generator regulator 20 with terminals 21a, 21b and 21c, a field coil 22 and a communication line COM and a stator with three stator windings 32 interconnected in a delta circuit at switching points 31a, 31b and 31c 30.
[0039] bridge rectifier 40 in figure 1 is shown as a six-pulse bridge rectifier 40 which is provided for rectifying the rotating current of the three-phase generator 20 , 30 . In the same way, however, it is also possible, for example, to use four-phase, five-phase, six-phase or seven-phase generators 20 , 30 and to use correspondingly adapted eight-pulse, twelve-pulse or fourteen-pulse bridge generators. Rectifier 40...
