Abstract:
An electric power conversion/inversion apparatus, comprising:a plural number of input bus bars for inputting electric power from an outside; a plural number of output bus bars for outputting electric power to the outside; and a plural number of semiconductor chips, being electrically connected to said input bus bars and said output bus bars for converting/inverting the electric power inputted into an output, wherein said plural number of input bus bars include a positive input bus bar and a negative input bus bar, being provided extending in parallel to each other, while said plural number of output bus bars are provided extending in parallel to each other and crossing over said positive and said negative input bus bars in longitudinal directions thereof, said plurality of semiconductor chips are disposed, being put between said positive input bus bar and said negative input bus bar and said plurality of output bus bars at crossing positions thereof, and connected electrically and thermally, to said positive input bus bar in a pole direction consistent therewith while to said negative input bus bar in a pole direction consistent therewith, and further to said common output bus bars in pole directions being different from side by side.
