Abstract: In order to detect post insulator and porcelain bushing with ultrasonic, according to the characteristics of insulator probe, creeping wave detection is recognized to be an effective ...

At the voltage of 500V, the drift length $(L_{d})$ of the high-voltage silicon-on-insulator (SOI) LIGBT can be shortened from $47 \mu m$ to $21.5 \mu m$ and the area of power stage in the single-chip ...
