Broadband Dielectric Properties and Temperature Effects of Silicone Gel for IGBT Device Encapsulation

open access: yesZhongguo dianli, 2020
Silicone gel materials are used as packaging material for IGBT devices. Under the operating conditions, the devices are subjected to a repetitive on-off voltage which corresponds to the wide spectrum, and the device loss will cause temperature rise.

Determination of a Dimensionless Fluctuation Coefficient Using Electrochemical Impedance Spectroscopy

open access: yesInternational Journal of Electrochemical Science, 2019
Using the Randles circuit model, we determined that, for the impedance to fall on a straight line in a Cole-Cole plot, a dimensionless fluctuation coefficient that represents the quantity of the fluctuation in ion concentration near an electrode must be ...
