1. A matrix converter comprising:

  • an AC capacitor including linearly arranged first, second and third terminals respectively formed in the three portions thereof;

    an IGBT including linearly arranged first, second and third input terminals respectively formed in the three portions thereof; and

    a bus bar for connecting together the three-portion terminals of the AC capacitor and the three-portion input terminals of the IGBT, whereinthe AC capacitor and the IGBT are disposed such that the linearly arranged terminals of the AC capacitor and the linearly arranged input terminals of the IGBT are parallel to each other and the first, second and third input terminals of the IGBT are respectively close to the first, second and third terminals of the AC capacitor, andthe bus bar is formed as a laminate bus bar provided in such a manner that three plate-shaped bus bars are laminated on top of each other and insulators are inserted between the respective bus bars as well as on the front and back surfaces of the bus bars,in the respective plate-shaped bus bars, there are provided internal terminals for connecting together the three-portion terminals of the AC capacitor and the three-portion input terminals of the IGBT, andthe terminals of the AC capacitor and the input terminals of the IGBT are connected together through the internal terminals.
