Abstract: 1294354 Automatic current regulation MARCONI INSTRUMENTS Ltd 10 April 1970 [10 July 1969] 34777/69 Heading G3X [Also in Divisions H3-5] High D. C. control voltages on telephone lines L1, L2 are diverted through a shunting circuit comprising two Zener diodes Z1, Z2, a field effect transistor FET and two resistors R1, R2, connected in series. The gate of the FET is connected to diodes D1, D2 and to the centre tags of high resistance R3, R4. The other end of the diodes and resistors are connected to the connecting point of the Zener diodes and resistors R1, R2. The diodes are connected back to back. In operation when the D. C. voltage on the line is low, audio signals pass to the split transformer secondary S and these signals have a peak voltage of 2 volts. When a control voltage of 50 volts appears on line L1, Zener diode Z1 conducts and current flows through R1 and D2 effectively connecting the gate G to the junction of R2 and Z2. Zener diode Z2 conducts to allow a constant current to flow between L1 and L2. If a high voltage appears on line L2 the circuit operates in a similar manner with Zener diode Z2 conducting first.
