Phase-field modeling and machine learning of electric-thermal-mechanical breakdown of polymer-based dielectrics

Nature Communications, 2019
Polymer dielectrics are promising for high-density energy storage but dielectric breakdown is poorly understood. Here, a phase-field model is developed to investigate electric, thermal, and mechanical effects in the breakdown process for a range of ...

Space Charge Modulated Electrical Breakdown [PDF]

Scientific Reports, 2016
AbstractElectrical breakdown is one of the most important physical phenomena in electrical and electronic engineering. Since the early 20thcentury, many theories and models of electrical breakdown have been proposed, but the origin of one key issue, that the explanation for dc breakdown strength being twice or higher than ac breakdown strength in ...
