摘要：This paper proposes a switching table based 2-level inverter and 3-level diode clamped multilevel inverter (DCMLI) for the purpose of direct torque control of induction motor. The proposed scheme determines the sector of reference vector and the voltage vector is selected from switching table to generate gating signals for the inverter. The 2-level inverter and 3-level DCMLI are used to explain this scheme. This can be extended to n-level inverter and to all major topologies. The performance measures in terms of total harmonic distortion (THD) and fundamental voltage of line voltage and phase voltage are computed and compared with and without filter. The results show that the performance is greatly improved by increasing the number of levels. The significant feature of the proposed scheme is that it can be utilized for direct torque control of induction motor with affecting its simplicity.
