<p>PROBLEM TO BE SOLVED: To provide a power converter capable of contriving effective cooling and miniaturization.SOLUTION: A power converter 200 includes: power modules 300U-300W which have built-in serial circuits 150; and a flow passage organizer 12 in the parallelepiped shape having a storage space 405 surrounded by a flow passage 19. The flow passage 19 has: a flow passage section 19a along a side face 12a of the flow passage organizer 12; a flow passage section 19b along a side face 12b; and a flow passage section 19c along a side face 12c. Then, the flat power modules 300U-300W are arranged in the flow passage sections 19b, 19a, 19c so as to become parallel with the side faces 12b, 12a, 12c in order. Thus, the planar view shape of the flow passage organizer 12 is made into approximately square, and the power converter 200 is miniaturized by arranging the power modules 300U-300W in the U-shapes so as to surround three directions of the storage space 405.</p> |
