Abstract—Speed control of slip ring induction motor (SRIM) has important aspect in adjustable speed drive applications. The power semiconductor technology has played a crucial role in the advancement of adjustable speed induction motor drives employing slip power recovery scheme (SPRS). For the narrow speed range, slip power is a fraction of the power rating of the induction motor, therefore, a lesser rating of converter and inverter certainly reduce size and cost of the drive. This paper presents the performance evaluation of MOSFET chopper and inverter controlled SPRS based IMD. The simulation model of IMD using MOSFET based buck-boost chopper and pulse width modulated voltage source inverter (PWMVSI) have been build up in MATLAB 2013b for performance evaluations. The performances of IMD have been investigated by taking in to account the parameters viz. power factor, efficiency and quality of supply in terms of total harmonic distortion (THD). The simulation results signify that the MOSFET chopper and PWMVSI controlled SPRS based IMD has higher power factor, efficiency and superior quality of supply with lesser THD in comparison of SPRS with SCR inverter control.
