Title (EN) CONTROL OF MULTI-LEVEL SUPPLY STAGE
(FR) COMMANDE D'ÉTAGE D'ALIMENTATION À PLUSIEURS NIVEAUX
Abstract:
(EN) There is described a buck-boost converter comprising: a voltage source; an inductor, wherein a first terminal of the inductor is switchably connected to the voltage source; and a plurality of capacitors switchably connected to a second terminal of the inductor, wherein a respective plurality of output voltages are formed across the plurality of capacitors, further comprising: an error determination means, for determining an error in each of the plurality of voltages, an inner control loop adapted to switchably connect one of the plurality of capacitors to the second terminal of the inductor in dependence on the determined errors; and an outer control loop adapted to control switching between buck mode and boost mode in dependence upon the determined errors.
(FR) La présente invention a trait à un convertisseur dévolteur-survolteur comprenant : une source de tension; une bobine d'induction, dont une première borne est connectée de manière à pouvoir être commutée à la source de tension; et une pluralité de condensateurs connectés de manière à pouvoir être commutés à une seconde borne de la bobine d'induction, une pluralité respective de tensions de sortie étant formées sur l'ensemble de la pluralité de condensateurs, comprenant en outre : un moyen de détermination d'erreur, permettant de déterminer une erreur dans chacune des multiples tensions, une boucle de commande interne conçue pour connecter de manière à pouvoir commuter l'un des multiples condensateurs à la seconde borne de la bobine d'induction en fonction des erreurs déterminées; et une boucle de commande externe conçue pour commander la commutation entre le mode de dévolteur et le mode de survolteur en fonction des erreurs déterminées.
