An apparatus and method therefor transfers electric charge between a charge storage device (25) and a first power terminal (11) having a plurality of first-nodes. The method interchanges charge between the charge storage device and a first first-node of the plurality of first-nodes through an inductive section (22), and, when a predetermined charge has been interchanged between the charge storage device and the first first-node, replacing the first first- node by a second first-node of the plurality of first-nodes. Charge is interchanged between the charge storage device and the second first-node through the inductive section. Preferably, the ratio of the charge interchanged between the charge storage device and the first first-node and the charge interchanged between the charge storage device and the second first- node is equal to a ratio of the currents drawn from the first first-node and the second first-node. Charge can also be interchanged between the charge storage device and a second power terminal (12) using a similar method.

L'invention concerne un appareil et son procédé d'utilisation, qui permettent de transférer une charge électrique d'un dispositif condensateur de charge (25) à une première borne d'alimentation (11) munie d'une pluralité de premiers noeuds. Le procédé de cette invention consiste tout d'abord à échanger une charge entre le dispositif condensateur de charge et un premier noeud faisant partie de la pluralité de premiers noeuds, et ce par l'intermédiaire d'une section inductive (22). Ce procédé consiste ensuite, une fois cette charge prédéterminée échangée entre le dispositif condensateur de charge et le premier noeud des premiers noeuds, à remplacer ce dernier par un second noeud de la pluralité de premiers noeuds, puis à échanger la charge entre le dispositif condensateur de charge et ce second noeud des premiers noeuds via ladite section inductive. Le rapport de la charge échangée entre le dispositif condensateur de charge et le premier noeud des premiers noeuds et la charge échangée entre le dispositif condensateur de charge et le second noeud des premiers noeuds est égal au rapport entre les courants débités par le premier et le second noeuds faisant partie de la pluralité de premiers noeuds. Enfin, la charge peut également être échangée entre le dispositif condensateur de charge et une seconde borne d'alimentation (12), selon un procédé identique.
