The invention relates to a device for electron energy transfer (1, 39) which comprises at least one current converter (4, 6, 40). Every current converter (4, 6, 40) has phase elements (10, 11, 12, 13, 14, 15, 27, 28, 29) with at least one series connection of circuit elements (10a...10i, 11a...11i, 12a...12i, 13a...13i, 14a...14i, 15a...15i, 10a'...10i', 11a'...11i', 12a'...12i') each that comprise at least two turn-off power conductors (22, 23) each and at least two free-wheeling diodes (24, 25), each connected in parallel thereto, and energy storing means (26). The aim of the invention is to improve the transfer properties in or between power distribution networks. For this purpose, the phase elements (27, 28, 29) comprise at least two respective parallel branches (7, 7'), connected in series thereto and having a respective series connections of circuit elements (10a...10i, 11a...11i, 12a...12i, 13a...13i, 14a...14i, 15a...15i, 10a'...10i', 11a'...11i', 12a'...12i').
La présente invention concerne un dispositif de transmission d'énergie électrique (1, 39) comprenant au moins un convertisseur de courant (4, 6, 40). Chaque convertisseur de courant (4, 6, 40) présente des éléments de phase (10, 11, 12, 13, 14, 15, 27, 28, 29) qui disposent respectivement d'au moins un montage en série d'éléments de commutation (10a...10i, 11a... 11i, 12a...12i, 13a...13i, 14a... 14i, 15a...15i, 10a' ... 10i', 11a' ... 11i', 12a' ...12i') comprenant chacun au moins deux semi-conducteurs de puissance déconnectables (22, 23), au moins deux diodes de marche à vide (24, 25) connectées parallèlement aux semi-conducteurs de puissance et des systèmes d'accumulation d'énergie (26). L'objectif de la présente invention est de mettre au point un tel dispositif avec lequel les caractéristiques de transmission dans/entre des réseaux de distribution d'énergie sont améliorées. A cette fin, les éléments de phase (27, 28, 29) présentent respectivement au moins deux embranchements parallèles (7, 7') qui sont montés en parallèle et qui comprennent respectivement un montage en série d'éléments de commutation (10a...10i, 11a... 11i, 12a...12i, 13a...13i, 14a... 14i, 15a...15i, 10a' ... 10i', 11a' ... 11i', 12a' ...12i').
