Abstract

In this paper a novel DIRECT TORQUE CONTROL algorithm based on switching table using three-level diode clamp inverter is introduced. Voltage deviation of DC link capacitors is one of the most significant problems of NPC three-level voltage source inverters. The voltage imbalance of DC link capacitors will result in low level harmonics, undesirable torque variation and motor efficiency reduction. To resolve this problem, a closed loop algorithm is introduced in this paper, in addition to its simple implementation; the algorithm is able to control the voltage fluctuation of DC link capacitors within the desirable limits. The result of simulation and experimental implementation confirms the performance of this method despite capacitors reduced capacity.
