Abstract

1402989 Automatic voltage control LUCAS ELECTRICAL CO LTD 12 July 1972 [17 Sept 1971] 43379/71 Heading G3R A semi-conductor voltage regulator, controlling the field winding current in a vehicle generator, is protected from transient effects, by a parallelconnected voltage dependent resistor. As shown, an alternator 11 charges a vehicle battery 14 at a regulated voltage determined by a potential divider 21, 22, Zener diode 23 and transistors 24, 26, 28. The alternator field winding 29 in series with the transistor 28 is connected in parallel with a voltage dependent resistor 34 which remains practically non-conducting during normal operation. Voltage transients, caused by ignition faults or disconnection, cause the resistor 34 to pass sufficient current to limit the current in transistor 28 to a safe value.
