Power Conversion Device

Abstract

A power conversion device (10) comprises: a first power conversion part (5) that converts a DC voltage applied from first and second capacitor units (40, 42) into a three-phase AC voltage; a second power conversion part (6) that converts a single-phase AC voltage or a three-phase AC voltage into a DC voltage and applies the DC voltage to the first and second capacitor units (40, 42); a first parallel flat plate conductor (30) having three flat plate-like conductors to which a high potential, an intermediate potential, and a low potential are applied from the first capacitor unit (40); a second parallel flat plate conductor (32) having three flat plate-like conductors to which a high potential, an intermediate potential, and a low potential are applied from the second capacitor unit (42); and a third parallel flat plate conductor (34) disposed on the side opposite to the first and second capacitor units (40, 42) across the first and second parallel flat plate conductors (30, 32).
