Abstract

A circuit configuration for controlling the field current of an alternating current generator in a vehicle electrical generator system includes a digital to analog converter for converting a digital command signal to an analog voltage. A first comparator compares the system field current with the converted analog voltage. A switched component, operatively connected to a power switch, is switchable in response to the comparator output. A frequency generator, operatively connected to the switched component, provides timed pulses to periodically tell the switched component to turn on the power switch.
