Abstract:
1. A method of controlling a generator including a stator having a plurality of salient poles, a rotor having a plurality of salient poles, and a winding wound around the stator, a quantity of the salient poles of the rotor being different than a quantity of the salient poles of the stator, said method comprising: executing an alternating mode by alternately repeating a supply mode for supplying power from a power source to the winding and a reflux mode for setting both ends of the winding to the same potential; and after said executing of the alternating mode, further executing the reflux mode, and thereafter executing a regenerative mode for recovering in the power source an electromotive force generated in the winding; wherein the generator is controlled by a switching circuit having a switching element and a diode connected to both ends of the winding, and the switching element is PWM controlled to execute the alternating mode.
