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