Abstract

L'invention concerne un procédé de commande d'un courant (ILOAD) traversant une charge (LOAD) comprenant les étapes suivantes : appliquer une première fonction de transfert (fPRED) représentative de la charge à une première tension (VCOM) pour obtenir une deuxième tension (VCOMPRED) ; appliquer la deuxième tension à une première borne (208) d'un circuit (201) de génération dudit courant ; prélever une troisième tension (VLOAD) entre des première (216) et deuxième bornes (218) de la charge ; comparer la troisième tension (VLOAD) à la deuxième tension (VCOMPRED) ; et déterminer le courant (ILOAD) à fournir à ladite charge en fonction du résultat de la comparaison.
