Abstract
1,025,874. Automatic voltage control. ROBERT BOSCH G.m.b.H. Oct. 22,1962 [Oct. 21, 1961], No. 39807/62. Heading G3R. A voltage regulator for a generator having a field winding 14 comprises a power transistor 23 in series with the field winding, a control transistor 24 responsive to output voltage for switching the power transistor, and a circuit for protecting the power transistor against overload. The protection circuit includes the series combination of a resistor 41 and a diode 40, acting as a voltagedependent resistor, connected in parallel with the field winding 14 and the emitter/collector path of the transistor 23; a potentiometer formed by a temperature compensating resistor 42 and a resistor 43 is connected across the diode 40, and the junction P of resistors 42,43 is connected over a diode 44 to the base of transistor 24. The arrangement is such that when an excessive current passes through a resistor 45 in the emitter/collector circuit of transistor 23 the increased voltage drop across this resistor gives, together with the voltage drop established by the diode 40 across resistor 42, an effective total voltage which renders diode 44 and transistor 24 conducting, whereby transistor 23 is switched off and protected from damage. A double diode may replace the two diodes 40, 44 (Fig. 3 not shown), and the circuit may include a third transistor (Fig. 4, not shown).
