Title: Improvements relating to regulation of direct current supplies
Inventor: MANNERS JOHN HUGH RUTLAND
IPC: H02M3/135
Filed: 1963-09-09
Abstract: 1,015,811. Automatic control of current and voltage. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Aug. 14, 1964 [Sept. 9, 1963], No. 35481/63. Heading G3R. A D.C. supply circuit includes switching means, connected between input and output terminals, to a control terminal of which is applied a switching signal whereby automatic regulation of the circuit output is effected. As shown, D.C. output terminals are supplied from an A.C. source by way of a rectifier MR1, a resistor R1, an inductor L2 and a controlled rectifier SCR to the triggering electrode of which is applied a control signal derived from a circuit including resistors R4, R5, a Zener diode MR2, capacitors L5, L6 connected in series across the output terminals, and resistors R6, R7 in parallel with C5 and C6 respectively. In operation, when the voltage across R6 falls to the reference voltage of diode MR2, SCR is triggered to conduction; an oscillatory discharge from a resonant circuit R3, L1, C1 subsequently renders SCR non-conducting again. The output voltage is thus stabilized at a predetermined value. A further diode in series with a further resistor may be connected in series between the junction of L2 and SCR and the junction of C5 and C6 to improve stabilization. The arrangement may be modified to regulate at a constant current by omitting resistor R7, so that resistor R6 senses the load current instead of the voltage across the load.
