Abstract: Inverter is a type of adjustable-speed drive used to control AC motor speed and torque. With advances in solid-state power electronic devices and microprocessors, various inverter control techniques employing pulse width modulation (PWM) are becoming increasingly popular in AC motor drive application. These PWM-based drives are used to control both the frequency and magnitude of the voltage applied to motors. This paper analysis the speed control system of Induction motor fed by voltage source Inverter with implementation of Proportional Integral (PI) controller in the feedback path utilizing constant volt per hertz ratio with two PWM techniques namely, sinusoidal PWM and Space vector PWM. Comparing the performance of SPWM and SVPWM based inverter has been analyzed in MATLAB/Simulink from the analysis of speed regulation, torque ripple and total harmonic distortion.
