Abstract:
1. A semiconductor control device comprising: 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, wherein 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, while correspondingly connecting with the both ends of the sidewall to open the internal space of the case to an outer area, wherein 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, and wherein the circuit board is positioned between the first semiconductor module and the second semiconductor module, in the internal space.
