Abstract
Induction motor demand is increasing day by day with increasing demand an essential requirement arises too inefficient motor controlling method. A comparison study of three diverse Pulse width modulation (PWM) techniques of 3-ϕ inverter for better performance of induction motor is presented here using MATLAB/Simulink. Sinusoidal PWM, Third Harmonic injected PWM (THIPWM), Space Vector PWM (SVPWM) techniques simulation is show here, Motor parameter like speed vs time, torque vs time, Output voltage (THD), Output current (THD) of an inverter was observed by changing the carrier frequency and motor drive load. Simulation result shows that SVPWM flaunt better performance comparing other PWM technique.
