1. An automobile generator apparatus comprising:

  • a single-shaft, dual-output type generator including a stator having slots, a rotor disposed inside said stator and driven by an engine of an automobile, a high-voltage coil and a low-voltage coil disposed within each of said slots, a field coil wound on said rotor for producing a magnetic field acting on said high-voltage coil and low-voltage coil to obtain a high-voltage output from an output terminal of said high-voltage coil and a low-voltage output from an output terminal of said low-voltage coil, and a first rectifier circuit connected to said output terminal of said low-voltage coil;

    a battery connected to said output terminal of said low-voltage coil and connected in parallel to electric equipment of the automobile for serving as an electric power source and supplying field current to said generator;

    a second rectifier circuit connected to said output terminal of said high-voltage coil for converting high AC voltage generated by said generator into DC voltage;

    a constant voltage stabilization circuit connected to an output side of said second rectifier circuit for adjusting DC voltage output from said second rectifier circuit to a constant value;

    an inverter unit connected to an output side of said constant voltage stabilization circuit and provided with an outlet into which a load is plugged, for converting DC voltage output from said constant voltage stabilization circuit into AC voltage having a household frequency; and

    a controller unit for supplying control field current to said generator in order to adjust low voltage output from said generator to a constant value on the basis of a low-voltage signal output from said generator.
