Power conversion device and power conversion unit

A power conversion device comprising:

• a housing having a floor, a ceiling provided above the floor, and a front face, a back face, and a pair of side faces that join the floor and the ceiling;
• an input circuit part, a power conversion unit, a reactor, and an output circuit part housed inside the housing;
• and
• an output terminal provided in the ceiling,
• wherein the input circuit part, the power conversion unit, the reactor, and the output circuit part are arranged in a planar direction of the front face so as not to overlap each other in a plan view of the front face,
• the input circuit part is provided above the floor,
• the output circuit part is provided below the ceiling and above the input circuit part,
• the power conversion unit is provided between the input circuit part and the output circuit part, and the reactor is provided beside or above the power conversion unit between the input circuit part and the output circuit part, and
• wherein, with an axis in a direction from the floor to the ceiling being considered as a vertical coordinate axis, the input circuit part, the power conversion unit, the reactor, and the output circuit part are connected in series in this order through a plurality of metal bus bars that each extend vertically,
• wherein the plurality of metal bus bars include:
• a first metal bus bar having a first end connected to the input circuit part, a second end connected to the power conversion unit, and a first central part extending straight between the first end and the second end vertically in a plan view of the front face;
• a second metal bus bar having a third end connected to the power conversion unit, a fourth end connected to the reactor, and a second central part extending straight between the third end and the fourth end vertically in a plan view of the front face;
• and
• a third metal bus bar having a fifth end connected to the reactor, a sixth end connected to the output circuit part, and a third central part extending straight between the fifth end and the sixth end vertically in a plan view of the front face.
