Summary:Disclosed generator includes magneto alternator and compensate controller. Two sets of main winding and compensation winding in same number of poles are installed on armature of the magneto alternator. Based on measured signal of main winding, current and voltage detector in compensate controller tracks magnitude, phase and frequency of armature current. Based on tracking signal, controller of inversion injects current controllable in phase, magnitude, and in identical frequency to current in main winding to secondary winding in order to provide excitation magnetic potential to main winding. Digital technique and technique of tracking current and voltage in real time adopted in compensate controller. The invention reaches high precision for adjusting terminal voltage of generator.
