BACKGROUND
Appellants’ invention is directed to an electrical power
supply system for use in an automotive vehicle for supplying power
to a high power load and a battery. An understanding of the
invention can be derived from a reading of exemplary independent
claim 1 which is reproduced as follows:
1. An electrical power supply system for an automotive vehicle
comprising:
an alternator having an armature winding and a field coil for
supplying a power to both a high power load and a battery,
a stepping-up DC/DC converter for stepping up a voltage of
said battery and applying a stepped-up voltage to said field coil,
a voltage control means for controlling an output voltage of
said alternator by controlling a current of said field coil, and
a control means for increasing power of said alternator by
changing said output voltage of said alternator in response to a
rotating speed of said alternator when said alternator supplies
power to said high power load, and for controlling said output
voltage of said alternator to a battery charging voltage by
regulating said voltage control means when said alternator supplies
power to said battery.
