A modulated generator voltage control device using an automatic voltage regulating circuit substrate is provided to be operated more steadily by classifying an automatic voltage regulating circuit into two parts. A generator(10) produces the AC power supply. The output voltage of the generator is controlled according to excitation coil current variance. A voltage converter(20) transforms AC power generated by the generator. A first voltage regulator(301) automatically regulates voltage to the transformed AC power by the voltage converter. A second voltage regulator(302) is connected to the first voltage regulator in parallel. The first voltage regulator consists of a DC voltage convert(32), a variable resistance part(33), a comparator(34), a reference voltage part(35), a triangle wave oscillator(36) and a driving amplifier(37). |
