Abstract

A DTC technique using NPC three level inverter fed induction motor is presented in this paper. In order to utilize the weak wind irrespective of the required constant angular velocity, a modified DTC with NPC topology can be used. Compared to the conventional DTC, this three level inverter DTC topology provides better dynamic performance with reduced torque ripple. Results obtained by using a versatile simulation package, SIMULINK/MATLAB, for demonstrating the NPC three level Inverter fed Induction motor with Direct Torque Control proves the effectiveness of the proposed topology.
