<P>PROBLEM TO BE SOLVED: To provide a power converter board that has high flexibility in selecting mounting positions of devices, including a mounting position of an outside wire connection terminal. <P>SOLUTION: A door of a cubicle-shaped board body and a backboard opposed to it are provided with a ventilation opening for intaking/exhausting cooling wind, respectively. In the board body, a plurality of unit cases which are stacked in multiple stages in the vertical direction for inserting and arrangement are provided. The devices constituting a power converter housed in the board body are classified into a plurality of groups by function, and the devices in groups are housed in the unit cases for each group, to constitute a plurality of function units. A function unit among the plurality of function units that includes a device requiring cooling is inserted at a position opposed to the ventilation opening in the cubicle, with a cooling fan provided on the front surface of the unit case to allow cooling air to flow from the front surface to the rear surface in the unit case. Other function units are inserted at arbitrary positions. <P>COPYRIGHT: (C)2010,JPO&INPIT |
