Abstract

A power conversion device includes a primary-side circuit, a first connection line and a second connection line, a first capacitor provided on the first connection line, a second capacitor provided on the second connection line, a secondary-side circuit. The secondary-side circuit includes a first leg and a second leg. The first leg includes a first coil and a first diode, which are connected in series to each other. The second leg includes a second coil and a second diode, which are connected in series to each other. An anode terminal of the first diode and an anode terminal of the second diode are electrically connected to a negative one of the two output ends. A cathode terminal of the first diode is electrically connected to the first coil. A cathode terminal of the second diode is electrically connected to the second coil.
