Power conversion apparatus
First Claim
1. A power conversion apparatus comprisingpower modules which include semiconductor elements constituting a power conversion circuit for converting powers between DC and AC;
- a control circuit board on which components constituting a control circuit for driving and controlling said semiconductor elements are packaged;
bus bars which connect said power conversion circuit and an external equipment; and
a base on which, at least, said power modules and said control circuit board are fixed,wherein said base includes a first fixation portion and a second fixation portion which are coupled to each other at an angle,wherein said power modules are fixed on said first fixation portion of said base,wherein a first principal surface of said control circuit board extends along the second fixation portion and is held in direct or indirect contact with said second fixation portion of said base, andwherein said components are packaged on a second principal surface of said control circuit board.

Abstract
A power conversion apparatus comprising a base which includes a first fixation portion and a second fixation portion that are coupled to each other at a desired angle, wherein power modules are fixed on the first fixation portion of the base, a control circuit board is fixed with its first principal surface held in direct or indirect touch with the second fixation portion of the base, and components constituting a control circuit are packaged on the second principal surface of 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.
