| Abstract | ||||
| Multilevel inverter technology has become the most appropriate utilization for high-power medium-voltage drives and transmissions. This paper includes a comparative analysis of the performance of 3-level and 5-level inverters connected to induction motor for power quality purposes. It's likely to show the benefits of increasing the number of levels in an inverter. A simple space vector modulation algorithm is used for this comparison. This algorithm is applied to Cascaded Multilevel inverter topology. Power quality of these schemes can be enhanced by eliminating the noisy harmonics. In order to reduce the total harmonic distortion of the resulted voltage waveform a passive filter is carefully designed. In this paper, simulation results are carried out using Matlab/Simulink software environment. | ||||
