Contribution to Power Quality Improving the DFIG Control Using a Reduced Components of Multi-level Inverter

摘要

One of the most efficient wind generators is the Double Fed induction Generator (DFIG). The key problem with power generation is the generation of that very low THD sinusoidal waveform at variable velocity induced by the two-level inverter used. This paper introduces a multi-level inverter designed to reduce the THD and the output filter size. A nine-level reduced part multilevel inverter was suggested in this paper. The results of the simulation demonstrating the efficiency of the proposed multi-level inverter are discussed.
