Power supply device and method of controlling the power supply device
A voltage control unit is configured to: control, in accordance with an output voltage signal and an output current signal, output power of a rectifying unit to a voltage lower than a voltage by which an amount of generated power of a magneto AC generator becomes maximum; control a transformation ratio in accordance with the output voltage signal and the output current signal so as to improve power generation efficiency of the magneto AC generator one of when an rpm variation signal indicates an decelerating state and when the rpm variation signal indicates that a variation in rpm indicates a value smaller than a predetermined constant; and control the transformation ratio so as to decrease the output power of the rectifying unit when the rpm variation signal indicates an accelerating state.
