Title
(EN) CUTTING ELECTRIC POWER CONVERTER
(FR) DISPOSITIF DE CONVERSION D'ENERGIE ELECTRIQUE A DECOUPAGE
Abstract
(EN)
The invention concerns a cutting device for reversibly converting electric power between an alternating voltage source (2) and an alternative current source (4), comprising switching cells (61, , 62n) each comprising first (81, , 82n) and second (101, , 102n) switches unidirectional in voltage and bidirectional in current. A first group of switches consists of the first switches (81, , 82n) of the switching cells connected in series between a first terminal (14) of the voltage source (2) and a first terminal (12) of the current source (4), and a second group of switches consists of the second switches (101, , 102n) of the switching cells connected in series between a second terminal (16) of the voltage source (2) and the first terminal (12) of the current source (4), the unidirectional characteristics in voltage of the first and second switches belonging to a first half of the cells being respectively opposed to those of the first and second switches belonging to a second half of the cells.

Ce dispositif de conversion réversible d'énergie électrique à découpage entre une source de tension alternative (2) et une source de courant alternatif (4), comprend des cellules de commutation (61, ..., 62n) comportant chacune un premier (81, ..., 82n) et un second (101, ..., 102n) interrupteurs unidirectionnels en tension et bidirectionnels en courant. Un premier groupe d'interrupteurs est formé par les premiers interrupteurs (81, ..., 82n) des cellules de commutation connectés en série entre une première borne (14) de la source de tension (2) et une première borne (12) de la source de courant (4), et un second groupe d'interrupteurs est formé par les seconds interrupteurs (101, ..., 102n) des cellules de commutation connectés en série entre une seconde (16) borne de la source de tension (2) et la première borne (12) de la source de courant (4), les caractères unidirectionnels en tension des premiers et seconds interrupteurs appartenant à une première moitié des cellules étant respectivement opposés à ceux des premiers et seconds interrupteurs appartenant à une seconde moitié des cellules.
