ELECTRIC POWER CONVERSION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an electric power conversion system which enables improvement of heat radiation performance of a capacitor cell and makes downsizing easy.SOLUTION: An electric power conversion system 1 includes: a case body 2 opening at the upper side; a capacitor cell 11 housed in a part of the case body 2; and a potting material 12 which seals the capacitor cell 11. The case body 2 includes: a cell storage space 31 which stores the capacitor cell 11 so as to enclose the capacitor cell 11 from a lower surface and a side surface and is filled with the potting material 12; and a connection space 32 which is connected with the cell storage space 31 and has a bottom surface at a position higher than a bottom surface of the cell storage space 31. An entire periphery of an integrated space 3 formed by the cell storage space 31 and the connection space 32 is enclosed by a space side surface 211 extending to a position higher than an upper end 111 of the capacitor cell 11.SELECTED DRAWING: Figure 2
