Performance Analysis of Induction Motor Utilizing SPRS Based on MOSFET/IGBT Cuk Converter Topologies

摘要

In slip power recovery scheme (SPRS) to avoid the wastage of slip power in rotor resistance, it is used as feedback to main power supply. Several types of topologies are used for SPRS, i.e., boost, buck, buck-boost and Cuk converter. Other than this, various switching devices like SCR, MOSFET, GTO, IGBT, etc., are used. Analysis of SPRS based on induction motor drive (IMD) utilizing MOSFET/IGBT Cuk converter and voltage source inverter based on IGBT with pulse width modulated scheme is carried out in the paper. Various performance analyses of IMD have been executed by utilizing the IGBT and MOSFET in converters. Wound rotor induction motor (WRIM) model based on SPRS utilizing pulse width modulated (PWM) scheme and voltage source inverter (VSI) has been developed using Simulink/MATLAB toolbox. The effect of duty ratio on speed, DC link current, supply current, source reactive power, supply power factor and total harmonic distortion (THD) has been investigated. IGBT produces better results as compared to MOSFET shown by simulation results.
