Abstract
973,440. Automatic voltage control. ROBERT BOSCH G.m.b.H. Nov. 16, 1961 [Nov. 26, 1960], No. 40973/61. Heading G3R. A voltage regulator for a shunt excited D.C. generator has a transistor in series with the field winding and a voltage and current responsive electromagnetic relay controls the transistor. The generator 16 supplies a battery 40 through a diode 45, and supplies the field winding 15 through a normally conductive transistor 50. The base current of transistor 50 energizes the voltage coil 53 of the electromagnetic relay which closes its contacts 51, 52 when the voltage of the generator reaches the prescribed value. These contacts short-circuit the base/emitter path of the transistor causing it to cut off, and a feed back resistor 60 applies the resulting self-induced voltage in the field winding 15 to the voltage coil 53 so that the relay opens earlier. Current limiting is effected by a coil 55 energized through a non-linear diode 56 across a resistor 44 in series with the generator load.
