Claim Text:
1. An electric power supply system comprising: an AC generator having a drooping characteristic; a rectification section for converting AC output of the AC generator to DC; a load having an electric storage device supplied with power from the AC generator; and a control section provided between the rectification section and the load, wherein the control section controls the AC generator so that the AC generator operates at a predetermined voltage lower than an output voltage corresponding to a maximum power operation point of the AC generator, and the control section controls the output voltage of the AC generator so that the output voltage starts from a voltage equal to or smaller than a rated input voltage of the control section, and then the output voltage of the AC generator converges to a constant voltage lower than the output voltage corresponding to the maximum power operation point of the AC generator as time elapses.
