Abstract

La présente description concerne un procédé comprenant les étapes successives suivantes : a) sélectionner (101) au moins une première tension (Vint) parmi un ensemble ordonné (100) de tensions continues (Vi), la première tension définissant des sous-ensembles de tensions continues ; b) comparer (102) la première tension à une tension continue de référence (Vref) ; c) sélectionner (103), en fonction du résultat de l'étape b), un desdits sous-ensembles ; et d) comparer (104) chaque tension du sous-ensemble sélectionné à la tension de référence.
