PROBLEM TO BE SOLVED: To provide a technology for achieving downsizing and reduction in weight, for a power converter in which a laminate formed by laminating a plurality of power cards and a plurality of coolers is pressurized.SOLUTION: A power converter 100 comprises a plurality of power cards 5, a plurality of coolers 3 and two stationary plates 7a and 7b. The two plates 7a and 7b are disposed at both ends of a laminate 2 that is formed by laminating the plurality of power cards 5 and the plurality of coolers 3. The laminate 2 and the two stationary plates 7a and 7b include through-holes that communicate in a direction of lamination. Bolts 11a and 11b are inserted into the through-holes of the laminate 2 and the two stationary plates 7a and 7b, and the bolts 11a and 11b are fastened by nuts 15a and 15b. The bolts 11a and 11b pressurize the laminate 2 in the direction of lamination.SELECTED DRAWING: Figure 1 |
