Abstract

A voltage source converter configured to generate at least two pulse trains using at least three voltage levels comprises a first arm (ua) between a junction (j) and a first DC terminal (DC1) having a first voltage level (Vdc/2), a second arm (1a) between the first junction and a second DC terminal (DC2) having a second voltage level (-Vdc/2) and a third arm (na) between the junction (j) and a neutral point (np) having a third voltage level (0) between the first and second voltage levels, wherein at least one of the arms (ua, 1a) comprises cells (Cua1, Cua2, Cua3, Cua4, Cla1, Cla2, Cla3, Cla4), each cell comprising a main switch, a first auxiliary switch and a snubber capacitor, where the main switches switch between two of the voltage levels and the auxiliary switches introduce a slope in the transition between the two levels; and the other arms (na) only comprise switches (S1, S2) for connecting the junction to a corresponding voltage level.
