SVPWM & SPWM CONTROLLER BASED PERFORMANCE EVALUATION OF THREE PHASE INDUCTION MOTOR

This paper presents the performance analysis of three phase induction motor using sinusoidal pulse width modulation(SPWM) and space-vector modulation(SVPWM). The main objective of this paper is to evaluate the power factor, efficiency and THD of three phase induction motor and compare the results using SPWM and SVPWM method. Space vector pulse width modulation (SVPWM) technique has emerged as a most used modulation strategy for the voltage source inverter (VSI) fed AC motor drives. This paper describes comparison of SVPWM and SPWM modulating techniques with induction motor as load. Switching strategies for the inverter based on space vector PWM (SPWM) and sinusoidal PWM (SPWM) is used in this paper.
