Abstract
A power conversion apparatus comprising a basewhich includes a first fixation portionand a second fixation portionthat are coupled to each other at a desired angle, wherein power modules IPM, IPMand IPMare fixed on the first fixation portionof the base, a control circuit boardis fixed with its first principal surfaceheld in direct or indirect touch with the second fixation portionof the base, and components constituting a control circuit are packaged on the second principal surfaceof the control circuit board. Owing to the configuration, a versatility for the installation of the power conversion apparatus on a vehicle becomes high, the vibration-proofness of the control circuit board is enhanced, and heats generated by the electronic components, etc. packaged on the control circuit board are sufficiently emitted.
