Abstract
The study of metallized capacitor behavior at high frequencies points out thepresence of series and parallel resonances that could lead to oscillations, perturbations andadditional losses in power electronics apparatus. Starting from an already establishedanalytical model of this resonance, we propose a method to elaborate equivalent circuitssuiting circuit simulators. These models should help further investigations on high frequencyproperties of decoupling and snubber capacitors in commutation cells.
