PROBLEM TO BE SOLVED: To provide a small inverter apparatus having durability against use accompanying by long term vibration. SOLUTION: A power substrate 20 is arranged at a base of a box-like module case 11, and a control substrate 30 becomes a lid of an opening part of the module case 11. Thus, the inverter apparatus 10 can be lowered since it is modularized. In the inverter apparatus 10, a capacitor 22 is installed between the power substrate 20 and the control substrate 30. A resin mold layer 12 covers the capacitor 22 and the capacitor 22 is fixed into the module case 11. Since the capacitor 22 is fixed into the module case 11 by the resin mold layer 12, durability against vibration is higher compared to conventional screwing. COPYRIGHT: (C)2010,JPO&INPIT

Abstract:
An elastic printed board (102) is provided so that stress applied by the silicon gel (101) is absorbed by the printed board (102). Further, the printed board (102) is formed to be so narrow that the stress may be escaped. On the other hand, the wires on which a high voltage is applied are patterned on respective printed boards. This serves to prevent discharge through the surface of the same printed board served as current passage. This design makes it possible to hermetically close the power module, prevent intrusion of moisture or contamination as well as displacement, transformation and crack of the cover plate (105).
