Abstract: front page image
(EN)A system for controlling a commutation of a load current is provided. The system comprises an AC-to-AC converter (106) that includes a plurality of switching elements (108), an energy source (102) that provides an oscillating voltage and is connected to the converter (106), an electrical load (104) connected to the converter (106), and a controller (112) that controls the converter (106), and monitors the oscillating voltage and the load current delivered to the electrical load (104). The controller (112) determines a plurality of machine states of the converter, each of the plurality of machine states representing a corresponding conducting set of the plurality of switching elements (108), and controls switching between the plurality of machine states based on polarity commutations of the load current in the electrical load (104) and polarity commutations of the oscillating voltage.
(FR)L'invention concerne un système de commande de commutation d'une charge de courant. Le système comprend un convertisseur (106) CA-CA qui comprend une pluralité d'éléments de commutation (108); une source d'énergie (102) produisant une tension oscillante et qui est connectée au convertisseur (106); une charge électrique (104) connectée au convertisseur (106); et un organe de commande (112) qui commande le convertisseur (106) et surveille la tension oscillante et le courant de charge fourni à la charge électrique (104). L'organe de commande (112) détermine une pluralité d'états d'automate fini du convertisseur, chacun de ceux-ci représentant un ensemble correspondant d'états conducteurs de la pluralité des éléments de commutation (108); et commande la commutation, entre la pluralité des états d'automate fini, selon les commutations de polarité du courant de charge de la charge électrique (104) et les commutations de polarité de la tension oscillante.
