A power conversion device 300 includes: an AC/DC converter section 10 which has an initial charging circuit 36 that initially charges a smoothing capacitor 22 provided at an output portion, and converts alternating current power into direct current power; a DC/DC converter section 11 which performs voltage conversion of direct current power supplied from the smoothing capacitor 22; and a control unit 5 which controls output of the AC/DC converter section 10 and output supplied from the DC/DC converter section 11. The control unit 5 performs a predetermined charging from the initial charging circuit 36 to the smoothing capacitor 22 at start-up of the AC/DC converter section 10, and starts the operation of the DC/DC converter section 11 after completion of charging, whereby the circuit can be protected from an inrush current at start-up. |
