Electric power conversion/inversion apparatus

摘要

In an electric power conversion/inversion apparatus, including, such as an inverter therein, for obtaining reduction in circuit inductance and wiring resistance therein by bringing small as a whole, having good installability and high reliability and efficiency of electric power conversion, as well, semiconductor chips (1) are disposed, being put between a positive input bus bar (14p) and a negative input bus bar (14n) and plural output bus bars (18) at crossing positions thereof, and are connected electrically and thermally, to the positive input bus bar (14p) in a pole direction consistent therewith while to the negative input bus bar (14n) in a pole direction consistent therewith, and further to the common output bus bars (18) in pole directions being different from side by side.
