Investigation of Torque Ripple in Voltage Source Inverter driven Induction Motor Drive operated with Space Vector based Harmonic Elimination Pulse Width Modulation Scheme

The lower order harmonic elimination using the space vector pulse width modulation (SVPWM) technique is possible by introducing the dwell time-division coefficient ’k’ in the space vector. In this paper, torque ripple analysis is carried out for the space vector-based harmonic elimination (SVHE) scheme. The obtained results are compared with the existing schemes, such as conventional and advanced bus clamping SVPWM schemes. Further, the obtained results are validated through simulation results. The SVHE scheme gives a lower torque ripple than the conventional and advance bus clamping schemes at higher modulation indices.
