Abstract
A power source unit for an automotive vehicle comprises an alternator, a rectification unit for converting an alternating current output of the alternator to a direct current, and outputting same through first and second output sections, a first power accumulation unit connected in parallel with a first load, for receiving a power supply through the first output section, a second power accumulation unit connected in parallel with a second load, for receiving a power supply through the second output section, an alternator output control unit for adjusting an output of the alternator depending upon a terminal voltage of the first power accumulating unit, to maintain the terminal voltage of the first power accumulating unit at a predetermined level, and a voltage control unit responsive to a drop in a terminal voltage of the second power accumulation unit to predetermined level, to permit a power supply to the second power accumulation unit through the rectification unit to thus maintain the terminal voltage of the second power accumulation unit at a predetermined level.
