Abstract

An electric generating device of the self-excited, self-regulated, brushless, synchronous type includes an alternator-exciter for producing an electrical output and an adjusting means for adjusting or setting the output voltage of the alternator-exciter substantially independently of the winding arrangement thereof to control the no-load or light load voltage of the electrical output. A deactivating device deactivates the adjusting control when maximum field current is demanded by a load.
