Abstract:
1. A device for providing a supply voltage for loads of a vehicle electrical system, comprising: a first generator; a first regulator unit allocated to the first generator and having a first output stage transistor; a second generator; and a second regulator unit allocated to the second generator and having a second output stage transistor; wherein each of the first and second output stage transistors is controlled by a pulse-width-modulated control signal generated in a regulator unit; wherein the device has a connection between the first and the second regulator unit via which the pulse-width-modulated control signal generated in the first regulator unit, or a control signal derived therefrom that describes a pulse-duty factor of the pulse-width-modulated signal, is supplied to the second regulator unit; and wherein, in the second regulator unit, a connection is provided via which the pulse-width-modulated control signal generated in the first regulator unit, or the control signal derived therefrom that describes the pulse-duty factor of the pulse-width-modulated signal, is capable of being forwarded to the second output stage transistor.
