Abstract
A silicon controlled rectifier is connected between the output of each stator winding of a conventional alternator and a terminal of a lower voltage battery, and a control electrode of each silicon control rectifier is connected to a switching control circuit for switching the silicon control rectifiers to switch stator current alternatively to a lower voltage battery or to a higher voltage battery connected across the alternator stator. A voltage regulator is connected between the alternator field coil and the lower and higher voltage batteries.
Claims3
A multi-voltage alternator, comprising
- (a) a plurality of interconnected alternator stator coils,
- (b) a rectifier bridge connected to the stator coils and arranged for connection across a battery system which includes batteries of higher and lower voltages,
- (c) controlled switching means forming a half bridge connected to the stator coils and arranged for connection to a lower voltage
- (d) electrical switching control means having an output connected to the control electrodes of the controlled switching means and an input arranged for connection across only a higher voltage battery, and
- (e) voltage regulator means having a sensing input and a field supply input, the sensing input being connected across the lower voltage battery and the field supply input being connected across the higher or lower voltage battery and an output connected to the alternator field coil.
