ABSTRACT:
A voltage regulator for a charging generator comprising an a.c. generator, a rectifier for converting the a.c. output of the a.c. generator to a d.c., a battery connected to the output of the rectifier, comparison means for comparing the battery voltage with a reference voltage of a reference voltage generation circuit and a power transistor controlled by the output of the comparison means and controlling a current flowing through a field coil of the a.c. generator.
The reference voltage generation circuit comprises a voltage divider connected to a constant voltage power source and providing its divided voltage as the reference voltage, a plurality of transistors connected in parallel with a part of the voltage divider, and conduction control means for controlling the transistor in accordance with the ambient temperature so that the reference voltage is determined in accordance with the ambient temperature.
