Abstract
The spatial resolution of space charge distribution measurement at high temperature was tried to be improved using a modified pulsed electro-acoustic (PEA) system. It is important to understand charge accumulation characteristic between insulating layers to develop actual power electric devices, at high temperatures. However, since the spatial resolution of the conventional PEA space charge measurement system is poor at high temperatures, it is necessary to improve the spatial resolution. Therefore, improving it by making a thin P(VDF-TrFE) film and applying it to a modified PEA system was carried out. To show the improvement effect, measuring the interface charge accumulation between the dried and humidified PI films was carried out.
