<P>PROBLEM TO BE SOLVED: To provide a substrate connection structure which reduces vibrations of substrates of an electric power conversion apparatus in the electric power conversion apparatus mounted on a transaxle having a motor generator and a transmission gear. <P>SOLUTION: An electric power conversion apparatus 20 is formed by arranging a power module 21, a drive substrate 22, a substrate bracket 23, and a control substrate 24 from the lower side and connecting the components with bolts 27, 28 and spacers 26. The substrate bracket 23 connects with the drive substrate 22 and the control substrate 24 at different positions, allows connection positions to be set for the respective substrates so that the vibration amplitude is reduced even if the substrates have different sizes, and fixes the substrates thereto. Further, providing a clamp in a connector inhibits the displacement of the connector which is caused by vibrations. <P>COPYRIGHT: (C)2013,JPO&INPIT |
