B6-VSI emulation-based DTC strategy dedicated to B3-VSI fed induction motor drives

The paper proposes a novel direct torque control (DTC) strategy for induction motor (IM) drives fed by (B3-VSI). The introduced strategy, noted DTCEmulB3, is based on the emulation of the operation of the conventional inverter (B6-VSI). This has been achieved thanks to a suitable combinations of the three voltage vectors intrinsically generated by the B3-VSI, leading to the synthesis of the six balanced voltage vectors of the B3-VSI. This approach has been adopted in the design of the look-up table of the proposed DTC strategy which considers a subdivision of the Concordia plan into six sectors. Simulation and experimental results have revealed that, thanks to the proposed DTC strategy, B3-VSI fed IM drives exhibit interesting performance. These have been experimentally validated.
