A three-phase current inverter, comprising:
- a first three phase switching unit and a second three-phase switching unit, each of the first and second three-phase switching units comprising:
- a conductive central area of a substrate;
- and
- three identical switching cells arranged around and radially spaced from the conductive central area with a symmetry of revolution of order 3, each of the three identical switching cells comprising at least one first electrically-controlled switch in series with at least one second spontaneous conduction switch,
- wherein the conductive central area defines an input terminal of the three-phase current inverter to which the three identical switching cells are electrically interconnected;
- and
- wherein the three identical switching cells of the first three-phase switching unit and the three identical switching cells of the second three-phase switching unit are electrically connected two by two, interconnection nodes connecting the first and second three-phase switching units defining three phase terminals.
