要約(英語): Space charge accumulation behavior in fullerene added epoxy resin is observed at high temperature under high voltage. Space charge accumulation is said that it strongly affect the dielectric breakdown of insulating materials. Since epoxy resins are used for sealing materials of power semiconductors, it is important that space charge does not accumulate in them even at high temperature under high electric field, in which the sealing materials are suffered in the actual usage of the power electric devices. Recently, the research on the space charge accumulation characteristics of insulating materials with nano size filler called nano-composites has been enthusiastic topics, because it has been reported that the amount of the space charge accumulation was reduced by adding some kind of nano-size filler to the insulating materials. Particularly, fullerene is remarkable because they can easily obtain high dispersibility and have high electron accepting properties. From the measurement results, it is found that the adding of fullerene is effective to prevent the space charge accumulation even at high temperature under high DC stress.
