Abstract : This work proposes a comparative analysis between classical twelve sectors direct torque control (12_DTC) and a new twelve sectors direct torque control (12_DTC_3L).This new strategy is using a neutral point piloted (NPP) three level inverter is compared to 12_DTC.Many simulation results are presented showing the two torques, flux and stator current distortions and harmonics. To conclude, a comparison between 12_DTC and 12_DTC_3L is given.

Keywords : 12_DTC, 12_DTC_3L, NPP, torque dynamic, stator current ,flux, performances.
