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.
