ABSTRACT:
The present invention provides an engine-driven synchronous power generator that selects the operation state with respect to the load of the power generator by controlling the revolution. The electronic governor4includes a target revolution determining unit10including a storage101for providing a constant target engine revolution irrespective of the load current, and a map102for providing the target engine revolution corresponding to the load. The target revolution corresponding to the revolution of no-load operation and loaded operation is set in the map102. The storage101or the map102is selected by operating a switch9. A governor motor14is controlled so that the actual engine revolution calculated in an engine revolution calculator7converges to the target revolution. An automotive voltage regulator (AVR)15for controlling the output voltage of the power generator1constant irrespective of the load is provided.
