ABSTRACT:
A power device of improved input power-factor, reduced high frequency noise with rush current upon power source connection restrained, reduced switching loss and improved circuit efficiency is provided by an arrangement in which an output of a full-wave rectifying circuit is subjected to a high-frequency interruption through a switching means, an energy accumulated in an inductor connected to the switching means is applied through another switching means to a smoothing capacitor, and a current from the full-wave rectifying circuit so as to flow to the capacitor is interrupted by still another switching means.
