    摘要： Downsizing, cost reduction, and a low inductance of an input/output circuit are to be achieved with a power converter in which a multilayer board having a power semiconductor module 500 and busbars 11, 12 is modularized. The positive busbar 11 and the negative busbar 12 for feeding main circuit current are provided on a surface of the multilayer board 100 on which a control device 10a is mounted. The positive busbar 11 and the negative busbar 12 are formed to be thicker that the metal layer wiring in each layer of the multilayer board 100. The positive busbar 11 is electrically connected to the 2nth layer wiring (n represents a positive integer) from the positive surface wiring of the multilayer board 100, and the negative busbar 12 to the 2n+1th layer wiring opposite to the 2nth layer wiring of the multilayer board 100, through via holes. As a result, current flows into the power semiconductor module 500 in opposite directions through the 2nth layer wiring and the 2n+1th layer wiring. Thus the inductance of the main circuit is reduced, and downsizing and cost reduction of the high-output power converter energized by a large current can be achieved.

    摘要： It is an object of the present invention to analyze heat transfers with a high degree of precision at a computation cost within a realistic range for a large-scale object such as an entire power-electronic system. In order to solve the problems described above, the present invention provides a numerical analysis system based mainly on a configuration for dividing the analysis area into at least two division areas, for analyzing at least one of the division areas by adoption of a finite element method or a boundary element method and for carrying out an analysis by adoption of a technique based on equivalent circuit approximation for at least one of the other division areas.
