<P>PROBLEM TO BE SOLVED: To provide a smoothing capacitor mounting structure for inverter apparatus, which allows a capacitor of capacity effective for smoothing to be built in without incurring the increase of elements or occurrence of wiring. <P>SOLUTION: A smoothing capacitor 7 is mounted together with a switching power module 13 on a main circuit board 11 and they are built in a casing 15. Hereby, as compared with the inverter apparatus where the smoothing capacitor is attached outside to the casing 15, the wiring length between the switching power module 13 and the smoothing capacitor 7 is shortened, and wiring impedance is made extremely small. As a result, it can reconcile actually the downsizing of the smoothing capacitor 7 and the building in the casing 15 by enabling the smoothing capacitor 7 to be used efficiently. <P>COPYRIGHT: (C)2009,JPO&INPIT |
