Popis: International audience; This paper aims determining the minimumdecoupling capacitor Cdec for a high speed switching cell. It isdetermined when any increase of its value does not decrease theovervoltage at turn off anymore. A simplified model is deducedfrom a full understanding of the switching cell behavior,including the effect of all stray inductances and all interactionswithin the switching cell. This model is used in an optimizationprocess in order to obtain directly the minimal value of Cdec.The methodology is validated in comparison with timesimulation, as well as using experimental results. It has be usedto analyze the impact of the switching cell parameters on theminimum value of Cdec: switching speed, stray inductances andadditional resistance are considered
