ABSTRACT:
A voltage regulator for a vehicle battery charging system includes a Darlington pair for controlling the switching of current through the field winding of a generator. The input transistor of the Darlington pair has its base connected to one input terminal of the regulator by a normally non-conductive Zener diode of breakdown voltage at least five times the nominal voltage of the system, to protect the Darlington pair against over-voltage transients.
