1. A variable frequency generator, comprising:

  • a main stator comprising of multi-phase armature windings;

    an exciter field winding,a rotating portion comprising exciter multi-phase windings, a main field winding, and an amplification component between the exciter multi-phase windings and the main field winding,wherein the amplification component operates at a variable duty cycle to maintain a phase voltage of the armature windings near independent of a shaft speed of the variable frequency generator; and

    a rotating controller,wherein the rotating controller interfaces with and manages operations of the amplification component.
