  • Patent number: 8953335
    Abstract: A semiconductor control device is provided with: a plurality of semiconductor modules each having a cooling member and a semiconductor element; a circuit board mounted with a control element that controls the plurality of semiconductor modules; and a case in which the plurality of semiconductor modules and the circuit board are respectively mounted. The case is provided with a cylindrical sidewall that forms an internal space within the case, and on both ends of the sidewall, a first opening and a second opening are correspondingly formed to be opposite to each other. The plurality of semiconductor modules include a first semiconductor module mounted on the sidewall on a side of the first opening, and a second semiconductor module mounted on the sidewall on a side of the second opening. The circuit board is positioned between the first semiconductor module and the second semiconductor module, in the internal space.
