摘要： The connection between the terminals of three-phase electric parts used in a matrix converter is simplified to thereby reduce the inductance between conductors. An AC capacitor and an 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 also that the three terminals of the AC capacitor and the three input terminals of the IGBT are situated close to each other. A bus bar is formed as a laminate bus bar which can be provided by laminating three plate-shaped bus bars on top of each other. In the respective plate-shaped bus bars, there are provided internal terminals for connecting together the mutually adjoining ones of the three-portion terminals of the AC capacitor and the three-portion input terminals of the IGBT, and the mutually adjoining terminals are connected together through the internal terminals.

摘要： In an electric vehicle inverter apparatus 100, a vehicle control controller 15 detects a switch open signal output from a collision detector 16 when the collision detector 16 is caused by a collision between electric vehicles to operate. Then, an inverter main circuit connection switch 10 of a high-voltage battery unit 8 is put into an open state. Thus, the direct-current power supply from a high-voltage battery 12 to a DC bus portion is interrupted. In addition, electric charges charged into a main circuit capacitor 7 are discharged by a forced discharge circuit portion 22b.
