<P>PROBLEM TO BE SOLVED: To prevent breakage of a pin-shaped terminal, in an inverter control device for fixing a control circuit substrate with the pin-shaped terminal provided on a power substrate. <P>SOLUTION: The power substrate 150 is equipped with a plurality of signal transmission terminals 210a, 210b, 220a and 220b for signal transmission and grounding between the control circuit substrate 160 and itself along each of a pair of opposed sides. The control circuit substrate 150 is electrically connected to the plurality of signal transmission terminals 210a or the like, and is fixed by soldering to the plurality of signal transmission terminals 210a or the like. The plurality of signal transmission terminals 210a or the like are also arranged in a plurality of rows along each of a pair of the sides. <P>COPYRIGHT: (C)2009,JPO&INPIT |
