Title: Pulse-generating circuits
Inventor: KNIGHT HENRY ARTHUR PHILIP
IPC: H03K5/00
Filed: 1958-05-15
Abstract: 821,814. Rectifying. MULLARD Ltd. May 15, 1958, No. 15654/58. Class 38 (2). [Also in Group XL (c)] A pulse generator circuit for the pulse control of a grid controlled thyratron rectifier or regulator comprises the cascaded connection of a saw-tooth waveform generator, a D.C. restorer which maintains either the negative or positive peaks of the saw-tooth at a predetermined D.C. level, a relaxation oscillator network and a cold cathode trigger tube. The network and tube function as a pulse generator the frequency of which is synchronized by the saw-tooth waveform Fig. 2 shows a circuit for producing output pulses which control a grid controlled rectifier. A polyphase A.C. supply produces across the secondary of three phase transformer TS a voltage which is half-wave rectified by network D5, D6, D7, the ripple components of which, as described in Specification 820,928, [Group XL (c)], produces a saw-tooth waveform by the charging of capacitor C6 through rectifier D4 on the negative peaks, the capacitor subsequently discharging through resistor R6. The saw-tooth waveform is D.C. restored by the action of diode D2, the negative peaks being restored to a voltage level depending on the setting of resistor R4. Diode D1 clips the positive peaks and network C3, R3 functions as a relaxation oscillator having a free-running frequency greater than the period of the sawtooth output required from the circuit. The waveform at point B causes cold cathode tube VT to trigger at a predetermined point to produce output pulses at secondary TO. Thus if a saw-tooth waveform is applied to point A of the circuit provided that the frequency of the output pulse at the cathode of tube VT is constant the phase angle at which triggering occurs will be shifted with respect to the sawtooth wave by altering the D.C. level at point A. Since the synchronizing waveform is locked to the A.C. mains cycle phase shift of the output pulse with respect to the mains voltage is obtained by variation of the D.C. level at A. Thus, as shown in Fig. 3, in which the saw-tooth synchronizing waveform is superimposed upon a portion on one cycle of the mains supply the position of the sawtooth wave with respect to the mains and thus the position of the output pulse produced at TO is determined by the setting of the potentiometer R4.

[Also in Division G3] An A.C. voltage regulating circuit, Fig. 1, has its input terminals 10, 11 coupled to its output terminals 22, 23 through a tapped transformer 14 and controlled saturable reactors 19, 20, each reactor being controlled in accordance with the distribution of control current between the reactor control windings 39, 40 and having its main winding 17, 18 connected between a common terminal 21 and a respective voltage tap 15, 16 of the transformer, so that a range of output voltage values is available between the upper limiting voltage of tap 15 and the lower limiting voltage of tap 16. The transformer may be either double wound or an autotransformer as shown. The distribution of current between the control windings is determined by transistors 43, 44 arranged in a complementary conducting relationship, the limits of operation being transistor 44 fully conductive with transistor 43 cut-off and vice versa. Each transistor is shunted across a respective control winding, the upper limit of output voltage from tap 15 being obtained when transistor 43 is cut-off so that reactor 19 is fully saturated and reactor 20 unsaturated. Similarly, the lower voltage limit from tap 16 is reached when transistor 44 is cut-off. The rectified outputs of a tapped secondary winding 28 of a further transformer 24 provide the control winding and transistor currents. A further secondary winding 50 supplies a voltage stabilizing bridge network 55 comprising fixed resistors 56, 57, 60 and a Zener diode 59, the output from the bridge being taken between terminal 62 and an adjustment potentiometer 58 to control the conductivity of a transistor 48 in the base circuit of transistor 43, and hence the conductivity of the latter transistor. Each control winding is shunted by a rectifier 41, 42 to suppress induced voltages and the bridge network is shunted by a smoothing capacitor 61. In a modification, Fig. 2 (not shown), the reactors are connected on the input side of the transformer 14.
