ABSTRACT:
A three-phase alternator has tapped armature windings, the tap points being connected to provide 12 V output and to a main battery. The end terminals of the armature windings are connected to an auxiliary rectifier, the output of which is connected to an auxiliary battery which is serially connected to the main battery, so that the two batteries are serially connected like the serial connection of the armature winding portions. A single voltage regulator, which may be connected to the auxiliary rectifier, or can be separately supplied by separately rectified current controls current flow through the field. The voltage regulator can be connected to the end terminals of the armature windings so that the field will be energized at the higher voltage level corresponding to the series voltages of both batteries, and permitting use of the auxiliary rectifier also as a field rectifier. A typical high voltage load in an automotive vehicle is the starter, used only intermittently and for short periods, but at high power levels.
