<p>PURPOSE:To prevent an output voltage of a generator at voltage rising time such as an operation starting initial time from overshooting by starting a voltage regulating operation in the rising portion of the output voltage of the generator. CONSTITUTION:When the output voltage of a generator G rises, the reference voltage VZ1 of the prescribed voltage level specified by a Zener voltage is formed at a connecting point A at relatively early time after rising the output voltage V0. As a capacitor Cs is charged, the DC voltage level of a connecting point C gradually falls from the level of the voltage VZ1 and becomes substantially stable when the charge of the capacitor Cs is completed. The pulsating voltage level of the detected voltage Vc divided by a voltage divider 7 from the voltage of the point B rises or falls the Zener voltage level of a Zener diode ZD to regulate the voltage.</p> |
