Abstract
A device converting electric power between a voltage source and a current source, comprising several stages (8i) of switching cells (10i,k) comprising each two switches (12i,k, 14i,k), capacitors (20i,k) associated with the cells (10i,k) arranged in a row (18k) increasing from current source (4), control devices (16i,k) each connected to a cell (10i,k) and elements for monitoring the control devices (16i,k) . The stages (8i) define two end groups and at least an intermediate group of switches, the two end groups comprising switches of each cell belonging respectively to the first and last stage connected in series, the intermediate group comprising pairs of switches (12i,k, 14i−1,k) of cells belonging to two neighbouring stages connected in series. Furthermore, the capacitors (20i,k, 20n,k) of a common row (18k) are transversely connected in series between the two end groups.
