Performance Analysis of a Three Phase Induction Motor Fed by Three Phase PWM VSI Using Variable Modulation Index

Mayur Agarwal, Deepak K. Joshi

Abstract

Today, pulse width modulation technique is one in all the foremost wonderful management methods of speed control of the induction motor. The aim is to regulate effectively the speed and torque. This paper deals with the comprehensive performance analysis of an induction motor (IM) supported by sinusoidal PWM strategy. The PWM method, which involves the modulation of conventional sinusoidal reference signal and a triangular carrier, is used to produce pulse width modulated output only for under modulation index which is fed by voltage source inverter (VSI). For the implementation of the proposed drive the MATLAB/SIMULINK environment has been used. In this paper the impact of the modulation index on the performance of the inverter has been viewed. The whole analysis is done for under modulation (i.e. ma‹1).
