<p>PURPOSE:To reduce the variation in the voltage by compensating not only the variation in the voltage but the variation in the voltage generated by a speed varying cycle of an engine on the basis of variation in a load. CONSTITUTION:A speed variation cycle detector 20 detects the speed varying cycle of an internal combustion engine to output a slope signal VS1 rising at the prescribed slope during at least rotating speed decreasing period, and an output volage detector 21 outputs a detection signal V0 corresponding to the average value from the output voltage of the output winding of a generator. A subtractor 22 calculates the signal V0 from the signal VS1 and outputs a slope signal VS2. An exciting command generator 24 applies an excitation command signal Va for instructing to excite the exciting coil during the period that the slope signal VS2 becomes a reference signal Vr or higher to a field current flow controller 25.</p> |
