Abstract
This invention is directed to an automatic voltage regulator for a seperately excited generator comprising a main AC generator including an armature winding and an exciting winding and an exciter of an AC magneto generator associated with the exciting winding of the main AC generator. The regulator comprises a single controlled semiconductor switching device disposed in parallel to the exciting winding of the main AC generator and an output voltage detecting and control signal generating circuit which is adapted to detect the output voltage of the main AC generator and to apply a control signal to the controlled electrode of the controlled semiconductor switching device when the output voltage of the main AC generator reaches more than a predetermined value. The exciter of the AC magneto generator has an operating frequency higher than that of the main AC generator whereby the output voltage of the main generator can be regulated in a minute manner.
