摘要:
A multilevel converter including, in particular, a capacitor (C1, C2, . . . , Cn) for each of its cells. The capacitors have nominal charge voltages proportional to their respective ranks in the converter. It also includes control means (BT, DA1, . . . , DAn, pe2, . . . , pen) organized to evaluate said voltage of the voltage source (VECn), and whenever it is insufficient, to suspend said nominal operation of the converter (SE) and to act on said switches (T1, T'1; T2; T'2; . . . ; Tn, T'n) in such a manner that initially, while said voltage of the voltage source is being established, it begins by charging all of the capacitors of the converter (C1, C2, . . . , Cn), after which said control means establish said nominal operation of the converter.
