Abstract
Three-level inverter is widely used in high voltage and high power occasions. In this paper, different modulation strategies used in three-level inverter are studied and analyzed. The harmonic characteristics of different modulation strategies were compared, and the respective relationship of harmonic characteristic, modulation degree and total harmonic distortion in different modulation strategies was obtained. The conclusion is validated by the results of simulation and experimentation.
