Title: Improved voltage stabilizer circuit arrangements

IPC: G05F1/563

Abstract: 1,058,160. Automatic voltage control. RANK-BUSH-MURPHY Ltd. Dec.1 1965 [Sept. 15, 1964], No. 37609/64. Heading G3R. A voltage stabilizer comprises an input source 1 to 9 of rectified A.C., a reservoir capacitor 11, a series transistor 12, an amplifier 14 for controlling transistor 12 in dependence upon variations in output voltage at terminals 13, 16, and a thyristor 15 associated with a pulse generator circuit responsive to the potential between the collector and emitter of the transistor 12. In operation, if the said potential increases because of the adjustment to a low value of the output voltage or because of an increase in the input voltage, the thyristor 15 is triggered at a later point in the half cycle of the applied A.C., whereby the potential across capacitor 11 is reduced and the voltage drop across the transistor 12 minimized; conversely, the triggering of thyristor 15 is advanced when the said emitter/collector potential decreases, whereby this potential is held nearly constant so that it is not necessary for the transistor 12 to be of the high-dissipation type. The pulse generator circuit includes an auxiliary voltage source +, - capacitors 17, 18 connected across the input source and a transistor 19 which is responsive to the emitter/collector potential of transistor 12 and which produces pulses having a width proportional to this potential; these pulses are applied to the control electrode of thyristor 15 by way of a differentiating circuit 24, 25, a transistor 26 and a capacitor 28.

Clock signals B in true and inverse form are passed by gates 42, 43, to constitute the transformer input pulses, the gates being enabled by a bi-stable 41 for the duration C of the input pulses A. The phase-modulated coding signals thus generated are decoded at a receiver (Fig. 4, not shown) by passing them through a high pass filter (31), an a.g.c. amplifier, and a threshold and limiting circuit (33, 34). A computer installation (12, 13, Fig. 6, not shown) sends and receives data via an interface circuit (12) using the above circuits. The "send" data SD (from 75) is sampled and stored (at 80) by clock (14) and divider (71), and fed (via 13) to the interface (12).
