Industry scholars solve the problem of silicone gel bubbles caused by the temperature rise of power devices
Due to its excellent electrical insulation and mechanical properties, silicone gel is widely used in the packaging insulation of IGBT devices. Xu Jiayu, Li Xuebao, Cui Xiang, Mao Yuan, and Zhao Zhibin, researchers from the State Key Laboratory of New Energy Power Systems (North China Electric Power University) and the Department of Electrical and Computer Engineering of Virginia Tech, published in the second issue of "Journal of Electrotechnical Society" in 2021 In the previous article, the preparation process of silicone gel was introduced in detail, the degassing curve was improved, and the problem of air bubbles at high temperature in samples prepared by traditional processes was solved.
