A New Methodology In SVPWM For Inverter Incite DTC-IM Drive

Multilevel inverters(MLI) brought renaissance in reduction of output voltage total harmonic distortions (THD). Conventional SVPWM (CSVPWM) based MLI are given better results in adjustable speed drives. With the number of levels increasing,complexity involved in the CSVPWM is also increasing.In the present work complexity involved in CSVPWM is minimized using the Rearranged-SVPWM. Torque of IM-Drive is controlled directly under variable speed applications using DTC strategy. Reduced stator current THD is achieved using Rearranged-SVPWM based DTC-IMD. To validate Rearranged-SVPWM, results are analysis is done and compared with CDTC-IMD, Rearranged-SVPWM based DTC-IMD performances.
