<P>PROBLEM TO BE SOLVED: To improve a wiring structure so as to thin a distribution board by reducing the wiring space of a bus-bar together with lowering of bus-bar impedance, in a main bus-bar to be wired between a smoothing capacitor unit and an inverter unit, which are separately accommodated in a line board. <P>SOLUTION: The power converter accommodates main circuit equipment including an inverter in a vertical self-standing distribution board 1 of a line board structure. The smoothing capacitor 5 and the inverter unit 6, which are connected to a DC intermediate circuit, are separately accommodated and disposed in the adjacent power supply board 2 and inverter board 3, and are wired via a horizontal bus-bar laid on the inside of the line board. The bus-bar is constituted of wide and thick belt-like bus-bars 7P, 7N and a bus-bar assembly 7 wherein insulation barrier plates 9, 10, 11 are overlapped on both surfaces of the bus-bar conductor to be integrated, and the bus-bar assembly 7 is wired by being inserted into the long holes 2c, 3c drilled in the rear side posts 2b, 3b of the line board. <P>COPYRIGHT: (C)2009,JPO&INPIT |
