## Abstract

A power conversion apparatus includes a plurality of power conversion units each including a power conversion module, the plurality of power conversion units being arranged at an interval in a lateral direction orthogonal to a vertical direction, and at least one support body that extends from one side toward the other side of the plurality of power conversion units in the lateral direction, on which the plurality of power conversion units are placed from above. The support body is formed from an insulating member.

## Claims

### Claim 1

A power conversion apparatus comprising:
a plurality of power conversion units each including a power conversion module, the plurality of power conversion units being arranged at an interval in a lateral direction orthogonal to a vertical direction; and
at least one support body that extends from one side toward the other side of the plurality of power conversion units in the lateral direction, on which the plurality of power conversion units are placed from above,
at least one support body being formed from an insulating member,
wherein the at least one support body includes an upper surface opposed to the plurality of power conversion units,
wherein the upper surface includes a first region where the plurality of power conversion units are placed and a second region located between adjacent power conversion units of the plurality of power conversion units,
wherein a height difference is provided between the first region and the second region,
wherein each of the plurality of power conversion units includes a slide guide that slidably holds the respective power conversion module in a front-rear direction orthogonal to the vertical direction and the lateral direction,
wherein the slide guide includes a mount portion that supports the respective power conversion unit of the plurality of power conversion units and a leg that supports the mount portion from below and abuts on the at least one support body, and
wherein the leg is located on an inner side of opposing ends of the respective power conversion module in the lateral direction when viewed in the front-rear direction.

### Claim 2 (depends on 1)

The power conversion apparatus according to claim 1, wherein
a portion of the upper surface located between the adjacent power conversion units of the plurality of power conversion units is provided with surface irregularities.

### Claim 3 (depends on 1)

The power conversion apparatus according to claim 1, wherein
the at least one support body includes a plurality of support bodies,
the plurality of support bodies are arranged as being aligned in the front-rear direction orthogonal to the vertical direction and the lateral direction, and
a length of each support body of the plurality of support bodies in the vertical direction is longer than a length of the respective support body of the plurality of support bodies in the front-rear direction.

### Claim 4 (depends on 1)

The power conversion apparatus according to claim 1, wherein
a plurality of basic units, each including the plurality of power conversion units and the at least one support body, are arranged as being aligned in the vertical direction.
