Abstract
A DC power-supply apparatus of converting an AC input voltage rectified to a DC voltage and supplying it to a load, by performing on-and-off control of a switching element connected in series to a reactor, includes a control circuit, which operates in floating state with respect to a after-rectified ground line and controls an on-width of the switching element based on a value of current flowing through the reactor and the load connected in series with the reactor; and an oscillation circuit, which controls a switching frequency of the on-and-off control by the control circuit, asynchronously with energy release timing of the reactor.
