Claim 5:
6. A power conversion device comprising:
a first power converter;
a second power converter; and
a stage in a shape of a flat plate, the stage having the first power converter and the second power converter mounted thereon, wherein
the first power converter includes a first semiconductor module and a first laminated bus bar connected to the first semiconductor module,
the second power converter includes a second semiconductor module and a second laminated bus bar connected to the second semiconductor module,
each of the first and second laminated bus bars is configured with the laminated bus bar of claim 1, and
the first power converter and the second power converter are arranged in alignment in the length direction such that the first end portion of the first laminated bus bar and the second end portion of the second laminated bus bar face each other in the length direction, and the respective fourth end portions are aligned in the length direction,
the power conversion device further comprising:
a DC positive bus that electrically connects the first positive DC terminal of the first laminated bus bar and the second positive DC terminal of the second laminated bus bar;
a DC negative bus that electrically connects the first negative DC terminal of the first laminated bus bar and the second negative DC terminal of the second laminated bus bar;
a first fuse connected between the first positive DC terminal of the first laminated bus bar and the DC positive bus;
a second fuse connected between the DC positive bus and the second positive DC terminal of the second laminated bus bar;
a third fuse connected between the first negative DC terminal of the first laminated bus bar and the DC negative bus; and
a fourth fuse connected between the DC negative bus and the second negative DC terminal of the second laminated bus bar, wherein
in a two-dimensional view as viewed from the width direction,
the first fuse and the second fuse are arranged in alignment in the length direction,
the third fuse is arranged in alignment with the first fuse in the thickness direction,
the fourth fuse is arranged in alignment with the second fuse in the thickness direction, and
the third fuse and the fourth fuse are arranged in alignment in the length direction.
