Abstract
A power conversion apparatus includes a plurality of power conversion units, a common bus bar, and a plurality of unit bus bars provided so as to correspond to the plurality of the power conversion units respectively and connecting each DC side of the plurality of the power conversion units to the common bus bar. Each of the power conversion units includes a casing having a first surface on which a first outer plate of a magnetic material is arranged, and the first outer plate is arranged in a vicinity of a corresponding unit bus bar and faces the corresponding unit bus bar with a gap so that an inductance value of the corresponding unit bus bar is increased to an inductance value capable of suppressing an inflow of a ripple current from another power conversion unit in the power conversion apparatus.
