| Abstract: |
| This article presents the direct torque control (DTC) strategy for the doubly fed induction motor (DFIM) connected
to two three-level voltage source inverters (3LVSIs) with neutral point clamped (NPC) structure. This control method
allows to reduce the torque and flux ripples as well as to optimize the total harmonic distortion (THD) of motor
currents. The use of 3LVSI increases the number of generated voltage, which allows improving the quality of its
waveform and thus improves the DTC strategy. The system modeling and control are implemented in Matlab/
Simulink environment. The analysis of simulation results shows the better performances of this control, especially in
terms of torque and flux behavior, compared to conventional DTC. |
