Abstract

1,092,129. Automatic voltage control. W.R. AIKEN. July 26, 1965 [July 27, 1964], No. 31734/65. Heading G3R. A voltage stabilizer includes a photosensitive resistor 12 responsive to a lamp 20 whose degree of illumination is dependent upon output voltage variations, so that changes in the alternating output voltage on line 18, caused by a varying input signal on terminal 14, produce corresponding corrective changes in the resistance of element 12 whereby the output voltage tends to remain constant. The lamp 20 is supplied from a source 9 by way of a transistor 22 which is controlled by a further transistor 26 responsive to output voltage variations as detected by a circuit R which includes a rectifier; the control voltage from transistor 26 is applied to the base of transistor 22 over a differentiating circuit 30, 32, 34, so that the arrangement is also responsive to the rate of change of voltage on output line 18.
