Abstract

Recent developments in power electronics and semiconductor technology have lead improvements in power electronic systems. A three-phase voltage source inverter provides variable voltage and frequency supply required by ac drives. For obtaining variable voltage supply pulse width modulation technique proves to be useful. Sinusoidal pulse width modulation is one of the popular techniques used for obtaining controlled output from inverters. In ac motor drives using SPWM inverters one can control both frequency and magnitude of the voltage and current applied to a motor. As a result, PWM inverter-powered motor drives are more variable and offer in a wide range better efficiency and higher performance when compared to fixed frequency motor drives. Three phase voltage-fed PWM inverters are gaining importance in various industrial applications. Sinusoidal Pulse Width Modulation variable speed drives are preferred in applications demanding superior performance .In this paper simulation and analysis of sinusoidal PWM Inverter fed Induction motor is carried out. The THD and fundamental voltage is measured at varying modulation indexes.
