Abstract
A power conversion device includes two input terminals, a first converter, and two first output terminals configured to output power converted by the first converter. The first converter includes a switching circuit, a flying capacitor, and a reactor. The power conversion device includes a second converter configured to perform power conversion on a voltage across the flying capacitor as an input voltage, two second converter input terminals electrically connected to two ends of the flying capacitor, and two second output terminals configured to output power converted by the second converter. The second converter includes a primary-side circuit and a secondary-side circuit. The second converter is an isolated DC/DC converter in which the primary-side circuit and the secondary-side circuit are electrically isolated from each other.
