چكيده فارسي :
This paper investigates the switching-table based
direct torque control (ST-DTC) drive of induction motors using a
three-level neutral-point clamped inverter. A novel optimized
switching table for ST-DTC is proposed regarding the effects of
motor speed and load on torque changes. Furthermore, for
deviation of neutral point voltage in three-level NPC inverter, an
innovative closed loop control method is introduced that is not
only straightforward in implementation, but is also capable of
restricting voltage fluctuations in the specified limit. Simulation
results are provided to confirm the performance of proposed
