1. A power conversion apparatus comprising:
a direct-current (DC) circuit; and
a power converter including a plurality of switching elements, the power converter converting power between the DC circuit and an alternating-current (AC) circuit by a switching operation of the plurality of switching elements, wherein
the DC circuit includes a first capacitor, a second capacitor, and a third capacitor connected in parallel, and the first capacitor, the second capacitor, and the third capacitor each have an identical shape of a rectangular parallelepiped,
the rectangular parallelepiped has a pair of first surfaces facing each other, a pair of second surfaces facing each other, and a pair of third surfaces facing each other,
each of the pair of first surfaces has a first side and a second side orthogonal to each other, each of the pair of second surfaces has the second side and a third side orthogonal to each other, and each of the pair of third surfaces has the third side and the first side orthogonal to each other,
the first side has a length not less than twice and less than three times a length of the third side,
each of the first capacitor and the second capacitor is arranged such that the pair of first surfaces thereof are perpendicular to an installation surface and the pair of second surfaces thereof are horizontal to the installation surface,
one of the pair of first surfaces of the first capacitor faces one of the pair of first surfaces of the second capacitor while being spaced apart from each other, and
the third capacitor is arranged such that
one of the pair of first surfaces thereof faces one of the pair of second surfaces of the first capacitor and one of the pair of second surfaces of the second capacitor while being spaced apart from each other, and
one of the pair of third surfaces thereof is flush with one of the pair of third surfaces of the first capacitor and one of the pair of third surfaces of the second capacitor.
