Abstract
A cutting device for reversibly converting electric power between an alternating voltage source and an alternative current source, comprises switching cells each comprising first and second switches unidirectional in voltage and bidirectional in current. A first group of switches consists of the first switches of the switching cells connected in series between a first terminal of the voltage source and a first terminal of the current source, and a second group of switches consists of the second switches of the switching cells connected in series beween a second terminal of the voltage source and the first terminal of the current source, 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.
