ABSTRACT:
A voltage control system for vehicles includes a power supply control circuit which allows power to be supplied to a voltage regulator circuit from a battery through a voltage detection line only when a key switch is turned on. The voltage regulator circuit controls the energization of a generator depending on the terminal voltage of the battery detected through the voltage detection line. The power supply control circuit includes a voltage divider circuit for detecting a voltage developed at an output terminal of an auxiliary rectifier associated with the generator when the connection of the output terminal to the battery is completed upon closing the key switch. The power supply control circuit also includes an output transistor controlled by the voltage detected by the voltage divider circuit and when the detected voltage reaches a predetermined level, the output transistor is rendered conductive and allows the supply of power from the battery to the voltage regulator circuit through the voltage detection line.
