Abstract
A plural-voltage power supply with a generator and a pair of storage batteries is disclosed for use in automotive vehicles. The two batteries are connected in series and a low voltage load circuit is connected across the lower battery and an intermediate voltage load circuit is connected across the series connection of the batteries. A high voltage load circuit is energized directly from the generator output and includes a load device adapted to be operated at a voltage corresponding to an adjustable power setting of the device. A high voltage regulator controls the generator output to provide a voltage high enough to meet the highest voltage requirement of any of the load circuits. An intermediate voltage regulator regulates the voltage across the intermediate voltage load circuit and a low voltage regulator regulates the voltage across the low voltage load circuit.
