    • 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.
    • 使用具有功率半导体模块500和母线11,12的多层板模块化的功率转换器来实现输入/输出电路的小型化,降低成本和低电感。 用于馈送主电路电流的正母线11和负母线12设置在安装有控制装置10a的多层板100的表面上。 正母线11和负母线12形成为使得多层板100的每层中的金属层布线更厚。正母线11从正极母线11与第2n层布线(n表示正整数)电连接 通过通孔将多层基板100和负母线12的表面布线连接到与多层基板100的第2n层布线相反的2n + 1层布线。 结果,电流通过第2n层布线和2n + 1层布线沿相反方向流入功率半导体模块500。 因此,主电路的电感减小,并且可以实现由大电流激励的高输出功率转换器的小型化和成本降低。
