Abstract:
    Especially, the invention is related to a voltage stabilizer. Sampling circuit of the stabilizer rectifies and divides the voltage fed back, and sends the processed voltage to operational amplifier, where the processed voltage is compared with reference voltage. After magnified by power amplification triode, the signal output from the operational amplifier drives the servomotor, which brings about positive and negative rotation of carbon brush on the automatic coupling voltage regulator so as to change ratio between primary and secondary of voltage regulator to adjust output voltage. The invention stabilizes the output voltage at set value. Features are: small size, goodly outline, providing functions of output time delay, over loading alarm, and power off protection for overvoltage, etc.
