| Abstract |
This paper presents the comparison of two cascaded multilevel inverter, with phase-voltage of the nine
levels and applied to drive an induction motor of 500kVA/4160V. Performance indexes used in hereinafter
in the comparison are semiconductors power losses, total harmonic distortion and first order
distortion factor. The comparisons are developed in three ways; in the first comparison the switching frequency
is found. It guarantees that the converters present the same efficiency. In the second comparison
the objective is finding the maximum switching frequency that it is gotten in each topology. Finally, in
the third comparison, the efficiency which both systems present the same output filter is found. |
