Abstract

The present invention is directed to an automatic voltage regulating system for an electric generator comprising a detection coil for detecting the output voltage of an AC generator. The voltage regulating system includes a detection circuit comprising a rectifying circuit for rectifying the output voltage of the detection coil, a smoothing circuit coupled to the detection circuit for smoothing the output voltage and a regulating circuit coupled to the output of the smoothing circuit for shifting the voltage load thereof, wherein the regulating circuit shifts the level of the voltage in the smoothing circuit by comparing the voltage in the rectifying circuit with the predetermined voltage to control the field current during the period of the shifting of the voltage level.
