Abstract
A power conversion device that constitutes a converter-inverter unit where a converter to convert AC power to DC power and an inverter to convert DC power obtained by conversion of the converter to AC power are connected in series. A capacitor unit including a capacitor cell to accumulate therein the DC power obtained by conversion of the converter is provided between the converter and the inverter. A first conductor electrically connected to one of electrodes of the capacitor cell and a second conductor electrically connected to the other electrode of the capacitor cell are drawn out from the capacitor unit, and the first conductor is connected directly to positive-side capacitor connection terminals and of the converter and positive-side capacitor connection terminals and of the inverter, and the second conductor is connected directly to negative-side capacitor connection terminals and of the converter and negative-side capacitor connection terminals of the inverter.
