Abstract
1,092,863. Automatic voltage control. MARCONI CO. Ltd. Aug. 7, 1964 [Nov. 11, 1963], No.44381/63. Heading G3R. A D.C. voltage stabilizer comprises input terminals 1, 2, output terminals 3, 4 and a series transistor 6 the impedance of which is controlled by a signal applied to its base so that the output voltage is maintained at a desired constant value, the control signal being dependent jointly on the output voltage, the load current, and the input voltage. The output voltage signal is derived from a voltage divider 10, 11, 12, the current-dependent signal from a resistor 7 and the input voltage signal from a potentiometer 17; these combined signals are applied to the base of a control transistor 14 having its emitter connected to a reference Zener diode 22 which is associated with a temperature compensating diode 23; the output from transistor 14 is applied over a further transistor 15 to control the transistor 6. A modification including an additional transistor and an additional Zener diode is described with reference to Fig. 2 (not shown).
