Abstract
The maintenance of ripple-free DC link voltage is obligatory for satisfactory performance of induction motor (IM) drives. Because the IM drives exhibit nowadays uses voltage source inverter (VSI) in the obverse end of IM which converts DC link voltage into variable AC voltage. This paper proposes an active front end (AFE) controlled elementary super-lift Luo converter (ESC) in the DC link of IM drive. Unlike a usual DC–DC converter, the suggested ESC enhances the performance of IM drive by offering undulation-less DC link voltage and also improves supply end power quality. Among various control schemes, the direct torque control (DTC) is broadly used scheme for IM drives. Hence, the proposed IM drive uses basic DTC model and the control parameters of DTC are correlated with DC link parameters mathematically. Finally, the simulation is conceded for the developed IM drive using MATLAB/Simulink software. The simulation observations such as DC link voltage, stator flux trajectory, electromagnetic torque and speed response of IM validates the superiority of the proposed IM drive using ESC.
