<p>PROBLEM TO BE SOLVED: To simplify the circuit configuration of the power supply-controlling device of a generator, and at the same time to inhibit sudden change in the driving torque of the generator caused by drastic fluctuation in a load. SOLUTION: When an electric load (5) becomes an overload, a MOS-FET (309) is turned on and off according to the output signals of clock and retriggerable clock pulse generators (306) and (307), respectively, and the on period of the MOS-FET (309) is accumulated and extended for each cycle of operation by the time difference (t2-t1) between the first and second, thus gradually bringing the level of the output voltage of an AC generator (1) closer to that of a reference voltage (VR), and hence inhibiting the sudden change in the driving torque of the AC generator (1) caused by the drastic change in the electric load (5). Each of a comparator (304), the clock and retriggerable clock pulse generators (306) and (307), and a driving control circuit (311) can be put together into a one-chip microcomputer by program control, thus simplifying the circuit configuration of the entire controlling device.</p> |
