Abstract

1,099,542. Automatic current control. EGYESULT IZZOLAMPA ES VILLAMOSSAGI RESZVENVTARSASAG. Jan. 6, 1965 [Jan. 6, 1964], No. 651/65. Heading G3R. [Also in Division G1] In a system for controlling the magnitude of a test current applied to the collector base junction of a transistor 1 in an avalanche breakdown test (see Division G1) the current provided by a generator 2 is monitored by a resistor Rm and the voltage thereacross applied via transformer T2 and diode D5 to an emitter follower circuit V 10 , V 11 and then rectified by diode D3. The rectified voltage is applied to a differential amplifier V 6 , V 7 and the error signal is passed via V 9 , V 8 to control the amplitude of the output from the pulse generating system into the transformer T1 and thence to the transistor 1.
