1. A generator apparatus, comprising:
- a generator including an exciter winding and phase windings;
a generator controller adapted to furnish a control voltage to the generator;
a rectifier bridge adapted to rectify phase voltages made available by the generator to make available a DC supply voltage for a switchable load on a DC supply voltage lead;
a detector unit adapted to recognize a load shutoff;
an energy reservoir; and
a first switch controllable by the detector unit and arranged between the DC supply voltage lead and the energy reservoir;
wherein the detector unit is adapted to switch the first switch to transmissivity after a load shutoff is recognized, so that energy produced by the load shutoff is stored in the energy reservoir.

Abstract
A generator apparatus includes a generator, a generator controller, and a rectifier bridge. A detector unit for recognizing a load shutoff is also provided. When a load shutoff is recognized, a switch is controlled to be transmissive so that energy produced by the load shutoff is stored in an energy reservoir. From there it can be fed back into the vehicle electrical system.
