ABSTRACT:
The present invention is intended for maintaining constant the output voltage of a synchronous magnetoelectric generator without reducing the efficiency of the synchronous magnetoelectric generator regardless of load variation. A magnetoelectric generating system in accordance with the present invention comprises a synchronous magnetoelectric generator, a synchronous phase modifier connected to the output side of the synchronous magnetoelectric generator, a voltage detector for detecting the output voltage of the synchronous magnetoelectric generator, a comparator for comparing the output of the synchronous magnetoelectric generator detected by the voltage detector and a reference voltage set by means of a voltage setting device, an exciting current regulating circuit connected to the field winding of the synchronous phase modifier, and a controller. The controller controls the exciting current regulating circuit according to the output of the comparator.
