PROBLEM TO BE SOLVED: To provide a power conversion device capable of dispensing with a snubber circuit, reducing the inductance of connection of a stack unit and capacitor unit, and making the stack unit and capacitor unit detachable.SOLUTION: A put-in movable plate 14b of a stack unit 10 is coupled, by a put-in bolt 14e, a prescribed distance apart from a put-in fixing plate 14a so that a conductive board 23 can be inserted, and contacted under pressure by turning the put-in bolt 14e in forward using the conductive board 23 of a capacitor unit 20 inserted between the put-in fixing plate 14a and the put-in movable plate 14b as pressure-contacting means. The pressure contact is released by turning the put-in bolt 14e in reverse. As a result, the stack unit 10 and the capacitor unit 20 can be detached by only turning the put-in bolt 14e, and the distance between the units can be shortened as well, making it possible to achieve a reduction in inductance and, hence, to achieve dispensing with a snubber circuit. |
