Abstract: This paper presents the performance analysis of 'induction motor drive' (IMD) utilising slip power recovery scheme (SPRS) with two and three level voltage source inverter (VSI) and buck-boost chopper employing gate turned off thyristor, metal-oxide semiconductor field effect transistor, insulated gate bipolar transistor as switching devices. A mathematical model of 2 hp, 400 V, 50 Hz, 1,440 rpm IMD has been developed and simulated in MATLAB. The performance parameters taken for induction motor drive are reactive power, power factor, efficiency, and total harmonic distortion (THD) of the supply. The novelty of proposed scheme lies in the implementation of simulation model of SPRS using three level inverter and buck-boost chopper from the dynamic model library of MATLAB/Simulink. The simulation results have shown that two-level VSI with chopper controller has enhanced the power factor and efficiency of IMD compared to the SPRS without chopper. The three-level inverter has reduced the reactive power consumption and THD, consequently, enhanced the quality of power supply.
