Induction generator system and method

A rotary induction machine comprising:

• a cylindrical stator;
• a rotor axially rotatably positioned in the center of said stator;
• rotor windings integral to said rotor;
• a three-phase energy winding integral to said stator and magnetically coupled to said rotor windings;
• a first three-phase auxiliary winding integral to said stator and magnetically coupled to said rotor windings and electrically isolated from said energy winding, said three-phase auxiliary winding comprising three branch windings electrically coupled forming three-phase electrical terminals;
• a first capacitor electrically coupled across each of said three-phase electrical terminals;
• a second capacitor coupled with a first branch switch across a portion of a first one of said three branch windings;
• a control circuit for gating said first branch switch in response to parameters of a first voltage corresponding to a first selected branch winding and parameters of a voltage and a current corresponding to said energy winding;
• a second three-phase auxiliary winding integral to said stator and magnetically coupled to said rotor windings and electrically isolated from said energy winding, said second three-phase auxiliary winding electrically isolated from and magnetically coupled to said first auxiliary winding, said second auxiliary winding comprising three branch windings electrically coupled forming three-phase electrical terminals;
• a fifth capacitor electrically coupled across each of said three-phase electrical terminals of said second auxiliary winding;
• a sixth capacitor coupled with a fourth branch switch across a portion of a first one of said three branch windings of said second auxiliary winding;
• and
• control signals from said control circuit gating said fourth branch switch in response to parameters of a fourth branch voltage of said second auxiliary winding and said parameters of said voltage and said current of said energy winding.
