Abstract:
1. A voltage inverter comprising: two input voltage terminals (V N−1 direct voltage generators which are connected in series between the two input voltage terminals (V two first commutation branches each connected between an output terminal (V a controller for the commutation cells of the two first commutation branches; 2N−4 other commutation branches which are each connected between one of the middle points (A N−2 pairs of diode cells, each pair of diode cells being connected between a middle point (Di) of one of the 2N−4 other commutation branches and a middle point (Dn−2+i) of a different one of the 2N−4 other commutation branches, each diode cell of the N−2 pairs of diode cells including at least one diode; the diodes of the diode cells of one pair of diode cells being series connected, in the same direction, and being connected together by a middle point (Bi) connecting two consecutive generators of the N−1 direct voltage generators; and a controller for effecting commutation of the commutation cells of said 2N−4 other commutation branches.
