First Claim
Patent Images
1. An alternating current system for a car, comprising:
- a field coil;
an armature coil having a three-phase connection to generate an alternating current output;
a rectifying device for rectifying the alternating current output;
a battery to be charged with the output of said rectifying device;
a voltage controlling device for turning on and off the field current passing to said field coil; and
a power source separate from said battery and separate from said rectifying device for supplying said field current;
wherein said field current is supplied separately from said rectified output, so as to produce an increased rectified output.

Abstract
Excitation of a field coil 2 is carried out by a separated power source 9 placed independent of a battery 8 to increase the output of a generator. A solar battery 10, a piezoelectric element 13 or a thermoelectric converting element 19 is used as the separately exciting means so that the output of the generator is increased for an exciting current effected by the separately exciting means.

9. An alternating current system for a car, comprising:
-
a field coil; an armature coil having a three-phase connection to generate an alternating current output; a rectifying device for rectifying the alternating current output; a battery to be charged with the output of said rectifying device; a voltage controlling device for turning on and off the field current passing to said field coil; a power source separate from said battery for supplying said field current; and a switch connected between said power source and said battery for comparing the voltage from said power source to a threshold value and supplying said field current from said battery when said voltage is below the threshold value and supplying said field current from said power source when said voltage is above said threshold value; wherein said field current is supplied separately from said rectified output when the voltage from said power source is sufficiently large, so as to produce an increased rectified output.
