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.
