An electric power converter includes a plurality of branches of switch units. A first stage, a second stage and a third stage of the converter are connected in series. The first stage includes first positive and negative branches, which are connected between a first output node and two first input nodes. The second stage includes three input nodes and positive and negative cells, each connected between a first input node and two second input nodes. The third stage includes third positive intermediate and negative branches, connected between the three second input nodes and three third input nodes. Capacitors are connected between the three second input nodes and between the three third input nodes.

Electric power converter

A device converting electric power between a voltage source and a current source, comprising several stages () of switching cells (,) comprising each two switches (,,), capacitors (,) associated with the cells (,) arranged in a row () increasing from current source (), control devices (,) each connected to a cell (,) and elements for monitoring the control devices (,) . The stages () 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 (,,) of cells belonging to two neighbouring stages connected in series. Furthermore, the capacitors (,,) of a common row () are transversely connected in series between the two end groups.
