Abstract

906,776. Automatic voltage control; protective arrangements. MARCONI INSTRUMENTS Ltd. April 6, 1961 [July 4, 1960], No. 23269/60. Class 38 (4). A transistor T1 in series between a voltage source at 1, 2 and a load at 3, 4 is controlled by an amplifier 16 to maintain the load voltage constant. A second transistor T2 is normally cut-off, but conducts when the voltage drop across resistor due to the load current 8 is sufficient to make the emitter positive with respect to the base. Current through resistor R9 is then diverted to transistor T2 reducing the base drive to transistor T1 and preventing excessive current flow through it.
