摘要：
This paper proposes a control to balance the voltages of Dc-link for three-level NPC converter. Several relevant characteristics of the converter are addressed, such as voltage capability, harmonic distortion, and power losses. Compared to other techniques, the level of harmonic distortion was lower and the semiconductor losses (conduction and switching), the result was closed to other techniques present in the literature. Experimental results as well as simulated ones are presented.
