  • Patent number: 8879256
    Abstract: An electric power conversion apparatus includes a plurality of semiconductor modules, a frame, a control circuit board, and a reinforcing and fixing member. Each of the semiconductor modules has a plurality of control terminals. The frame receives the semiconductor modules therein. The frame has, at least, a pair of side walls that face each other with the semiconductor modules interposed therebetween. The control circuit board is located outside of the frame and has the control terminals of the semiconductor modules connected thereto. The reinforcing and fixing member extends to connect the side walls of the frame, thereby reinforcing the frame. The reinforcing and fixing member also has the control circuit board fixed thereto so that the reinforcing and fixing member is positioned between the control circuit board and the semiconductor modules.
