Abstract
The present invention related to a voltage-stabilizing circuit in the power supply apparatus of automobiles, and comprising a battery, a voltage-stabilizing capacitor, and a switching circuit. The battery provides a voltage; the voltage-stabilizing capacitor couples to the battery, and stabilizes the output voltage of the power supply apparatus of the automobiles; and the switching circuit opens the circuit between the voltage-stabilizing capacitor and the battery when the voltage of the battery is detected to be smaller than a threshold value. Thereby, power consumption of the battery is reduced, and the voltage-stabilizing capacitor is protected and thus the lifetime thereof is lengthened.
