Abstract

A DC power supply device (100) includes a rectifier (10) which converts AC current into DC current. The DC power supply device (100) includes: a first smoothing capacitor (Cd) connected in parallel to a large load circuit (Lo1); a first inductor (Ld) connected in series to the input side of the large load circuit (Lo) and the first smoothing capacitor (Cd) at the output side of the rectifier (10); a second smoothing capacitor (Csw) connected in parallel to a small load circuit (Lo2) at the output side of the rectifier (10); and a diode (Dsw) connected in series to the input side of the small load circuit (Lo2) and the second smoothing capacitor (Csw) at the output side of the rectifier (10).
