Abstract
A power conversion deviceincludes: an AC/DC converter sectionwhich has an initial charging circuitthat initially charges a smoothing capacitorprovided at an output portion, and converts alternating current power into direct current power; a DC/DC converter sectionwhich performs voltage conversion of direct current power supplied from the smoothing capacitor; and a control unitwhich controls output of the AC/DC converter sectionand output supplied from the DC/DC converter section. The control unitperforms a predetermined charging from the initial charging circuitto the smoothing capacitorat start-up of the AC/DC converter section, and starts the operation of the DC/DC converter sectionafter completion of charging, whereby the circuit can be protected from an inrush current at start-up.
