Abstract
This electric-power supplying device comprises switching elements, rectifying elements, and a control circuit. The switching elements are switched according to a switching pulse so as to perform a rectification. The rectifying elements are connected in parallel with the switching elements so as to perform a rectification. The control circuit alters the switching pulse gradually upon switching between the rectification performed by the switching elements and the rectification performed by the rectifying elements.
