Abstract

L'invention concerne un convertisseur de puissance électrique (1) qui comprend une pluralité de branches d'unités de commutateur. Un premier étage (2), un second étage (3) et un troisième étage (4) du convertisseur (1) sont connectés en série. Le premier étage (2) comprend des premières branches positive et négative (21), qui sont connectées entre un premier nœud de sortie (23) et deux premiers nœuds d'entrée (24, 25). Le second étage (3) comprend trois nœuds d'entrée (37, 38, 39) et des cellules positive et négative (31, 32), chacune connectée entre un premier nœud d'entrée (24, 25) et deux seconds nœuds d'entrée (37, 38, 39). Le troisième étage (4) comprend des troisièmes branches positive, intermédiaire et négative (41, 42, 43), connectées entre les trois seconds nœuds d'entrée (37, 38, 39) et trois troisièmes nœuds d'entrée (44, 45, 46). Des condensateurs (51, 52, 53, 54) sont connectés entre les trois seconds nœuds d'entrée (37, 38, 39) et entre les trois troisièmes nœuds d'entrée (44, 45, 46).The invention relates to an electric power converter (1) comprising a plurality of branches of switch units. A first stage (2), a second stage (3) and a third stage (4) of the converter (1) are connected in series. The first stage (2) comprises first positive and negative branches (21), which are connected between a first output node (23) and two first input nodes (24, 25). The second stage (3) includes three input nodes (37, 38, 39) and positive and negative cells (31, 32), each connected between a first input node (24, 25) and two second nodes. 'entry (37, 38, 39). The third stage (4) comprises third positive, intermediate and negative branches (41, 42, 43), connected between the three second input nodes (37, 38, 39) and three third input nodes (44, 45 , 46). Capacitors (51, 52, 53, 54) are connected between the three second input nodes (37, 38, 39) and between the three third input nodes (44, 45, 46).
