Abstract :
The paper deals with the impact on the 3-wire feeding network of induction motor drives using direct torque control (DTC). Harmonic and interharmonic content of line currents is evaluated with reference to high-power drives (about 1 MW) with IGBT-voltage source inverter (VSI). The most common kinds of DTC algorithms are considered, and their performances both on motor-side and line-side are compared in a wide range of the motor speed. Results of numerical investigations highlight the different influence of the DTC methodologies on line current interharmonics at different motor speeds and give useful information for properly sizing the input filters.
