ELECTRONIC DEVICE FOR REGULATING THE VOLTAGE OF ALTERNATORS, PARTICULARLY FOR MOTOR VEHICLES

摘要

An alternator for a motor vehicle is provided with an electronic device for regulating output voltage. The field winding of the alternator is energized through a power circuit controlled by an SCR triggered by a control circuit when voltage drops below a preset value. The triggering signal to the SCR and initial flow in the field winding through the SCR is governed by-the control circuit. Initial current flow in the field winding also takes place through an indicator lamp connected for battery recharging. The control circuit output applied to the SCR is also connected through a diode to the anode of a medium power SCR connected to one phase of the alternator.
