Efficiency Evaluation of Electrodes Segmentation Patterns for Metallized Film Capacitors

The novel types of electrodes segmentation patterns for metallized film capacitors were suggested. Electrodynamic destruction of segmented electrodes due to self-healing process was numerically calculated using COMSOL Multiphysics software. The dependence of electrodynamic destruction energy versus destruction time was used as a criterion of segmentation pattern efficiency. Advantages and disadvantages of novel electrodes segmentation types were determined. It was found that bridge-diamond segmentation is the most effective patterns configuration.
