This is a multi-level converter comprising at least one arm (B) formed of n stages (Et1, Et2, . . . , Etn) mounted in cascade. The first stage (Et1) comprises a single switching structure (Ce10) with four voltage levels and an ith stage (i lying between two and n) comprises i identical switching structures (Cei1, Cei2, . . . Ceii) with four voltage levels, mounted in series. Each switching structure with four voltage levels comprises a cell of floating capacitor type (T1, T2, T1′, T2′, C12), two basic switching cells (T3u, T3′u; T3l, T3′l) and a capacitive divider bridge (C9, C10, C11), the basic switching cells being connected between the voltage divider bridge and the cell of floating capacitor type.
