Abstract

793,181. Automatic voltage and current control systems; rectifying. STANDARD TELEPHONES & CABLES, Ltd. Dec. 3, 1954 [Dec. 11, 1953], No. 34567/53. Classes 38 (2) and 38 (4). A thyratron, controlled in accordance with output current and/or voltage, replaces one of the metal rectifiers in a bridge-connected network of metal rectifiers. The bridge, consisting of thyratron V1 and metal rectifiers MR1, MR2, MR3 is connected in series with a condenser C1 across the A.C. input. An amplified error signal is obtained from the D.C. output voltage tapped off Rv or output current taken off shunt Rc and fed back to the grid of the thyratron. The amplifier is a double triode, Fig. 7 (not shown). In a modification, Fig. 5 (not shown), the output of the controlled rectifier bridge is augmented by an auxiliary rectifier in parallel with it, the auxiliary rectifier being supplied from a current transformer in the A.C. supply to the main rectifier. In another modification, Fig. 6 (not shown), the output of the controlled rectifier bridge is augmented by an auxiliary rectifier in series with it, the auxiliary rectifier being supplied from an additional winding on the main supply transformer. In another modification, Fig. 9 (not shown), a current transformer in the main supply applies a transient current signal to the thyratron con. trol amplifier so as to improve stability. According to the Provisional Specification, the controlled thyratron may replace a metal rectifier in a voltage doubler, which in Fig. 1 (not shown), also has a voltage boost from a series auxiliary rectifier, in Fig. 2 (not shown), has automatic changeover from constant voltage to constant current control to provide " knee-curve " regulation; in Fig. 3 (not shown), the voltage boost is replaced by current boost; in Fig. 8 (not shown) the voltage doubler alone has transient feedback to improve stability and in Fig. 10 (not shown) the control voltage applied to the thyratron is limited by a biased diode clipper. Specifications 560,230, 622,230 and 665,335 are referred to.
