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 governorincludes a target revolution determining unitincluding a storagefor providing a constant target engine revolution irrespective of the load current, and a mapfor 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 map. The storageor the mapis selected by operating a switch. A governor motoris controlled so that the actual engine revolution calculated in an engine revolution calculatorconverges to the target revolution. An automotive voltage regulator (AVR)for controlling the output voltage of the power generatorconstant irrespective of the load is provided.
