Abstract :
In the paper a new three-level converter is presented. The proposed topology was named 3L-ASNPC (Active-Stacked-NPC) and its main advantage is the reducing of the average switching frequency for all power devices. In the same time, the apparent switching frequency of the output voltage is naturally doubled. Experimental results are shown in the paper in order to validate the proposed topology and the analysis of the switching states.
