CA 2743085
There is described a multilevel electric power converter circuit comprising: N s switching elements connected in series in a closed loop; NAE additional elements, the additional elements being one of a direct current source and at least one passive element, connected within the closed loop such that each additional element is connected to four of the switching elements, the ratio of a number of additional elements N AE to a number of switching elements N s corresponding to N s = 2N AE + 2; and one of a load and an alternating current source connected across the closed loop at nodes between adjacent switching elements that are separate from nodes to which the additional elements are connected.
L'invention porte sur un circuit convertisseur de courant électrique multiniveau comprenant : Ns éléments de commutation connectés en série en une boucle fermée; NAE éléments supplémentaires, les éléments supplémentaires étant un élément choisi entre une source de courant continu et au moins un élément passif, connecté dans la boucle fermée de telle manière que chaque élément supplémentaire est connecté à quatre des éléments de commutation, le rapport d'un nombre d'éléments supplémentaires NAE sur un nombre d'éléments de commutation NS correspondant à NS = 2NAE + 2; et un constituant choisi entre une charge et une source de courant alternatif connectée aux bornes de la boucle fermée au niveau de nuds, entre des éléments de commutation adjacents qui sont séparés de nuds auxquels les éléments supplémentaires sont connectés.
