Harmonics in induction motor
WebThe validity of the analysis was confirmed by simulations and experiments using an open-end winding induction motor (OEWIM). The voltage THD is reduced by maximizing MI of both inverters; experimental results show that the DPWM reduced the voltage THD from 1.29 to 1.18 and 2.06 to 1.89 at 0.50 p.u. and 0.25 p.u. of the rated-voltage compared ...
