| 摘要 |
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 governor 4 includes a target revolution determining unit 10 including a storage 101 for providing a constant target engine revolution irrespective of the load current, and a map 102 for 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 102 . The storage 101 or the map 102 is selected by operating a switch 9 . A governor motor 14 is controlled so that the actual engine revolution calculated in an engine revolution calculator 7 converges to the target revolution. An automotive voltage regulator (AVR) 15 for controlling the output voltage of the power generator 1 constant irrespective of the load is provided.
