Title: Improvements in or relating to stabilised d.c. supply power packs
IPC: G05F1/573
Filed: 1962-07-04
Abstract: 957,548. Protective circuits. TELEFUNKEN PATENTVERWERTUNGS G.m.b.H. July 4, 1962 [July 6, 1961], No. 25641/62. Heading H2H. [Also in Division G3] A D.C. voltage regulator of the series transistor type includes a protective circuit comprising an auxiliary transistor which, when conductive, completes a shunt path by-passing the control transistor. As shown, an output voltage at terminals I, II is stabilized by a series transistor 4 controlled, over an amplifying transistor 11, by an error signal developed in a transistor 8 which compares a reference voltage, derived from a Zener diode 9, with a fraction of the output voltage derived from a potentiometer 6. An auxiliary transistor 2 is connected with its emitter-collector path in a circuit in parallel with the base-emitter path of the series transistor 4, the base bias for transistor 2 being taken from a voltage divider 1, 3, which may be temperature compensated and one end of which is connected either to one input terminal T1 or to an additional terminal T2. The voltage divider 1, 3 is so dimensioned that transistor 2 is blocked when transistor 4 is operating within its permissible load range, the transistor 2 being rendered conductive only when the output voltage falls below a predetermined value, e.g. on short circuit. When conductive, transistor 2 completes a shunt path by-passing transistor 4, the shunt path comprising the transistor 2, the transistor 11 and a current limiting resistor 5 which is so chosen as not to affect the normal operation of transistor 11. The transistor 4 is thus protected against overload, the arrangement becoming fully operative once normal conditions are restored.
