Abstract: The 3L-NPC (Neutral-Point-Clamped) is the most popular multilevel converter used in
high-power medium-voltage applications. An important disadvantage of this structure is
the unequal distribution of losses among the switches. The performances of 3L-NPC
structure were improved by developing the 3L-ANPC (Active-NPC) converter which
has more degrees of freedom. In this paper the switching states and the loss distribution
problem are studied for two PWM strategies in a STATCOM application. The PSIM
simulation results are shown in order to validate the studied PWM strategies.
