Simulation Analysis of SVPWM Inverter Fed Induction Motor Drives
ABSTRACT:
In this paper represent the simulation analysis of space
vector pulse width modulated(SVPWM) inverter fed Induction motor drives. The
main objective of this paper is analysis of Induction motor with SVPWM fed
inverter and harmonic analysis of voltages & current. for control of IM number
of Pulse width modulation (PWM) schemes are used to for variable voltage and
frequency supply. The most commonly used PWM schemes for three-phase voltage
source inverters (VSI) are sinusoidal PWM (SPWM) and space vector PWM (SVPWM).
There is an increasing trend of using space vector PWM (SVPWM) because of it
reduces harmonic content in voltage, Increase fundamental output voltage by 15%
& smooth control of IM. So, here present Modeling & Simulation of SVPWM
inverter fed Induction motor drive in MATLAB/SIMULINK software. The results of
Total Harmonic Distortion (THD), Fast Fourier Transform (FFT) of current are obtained
in MATLAB/Simulink software.

CONCLUSION:
The
SVPWM Inverter fed induction motor drive Modeling & then simulation is done
in MATLAB/SIMULINK 12. From simulation results of THD & FFT analysis
concluded that SVPWM technique is better over all PWM techniques which gives
less THD in Inverter current 4.89%., which under the permissible limit.
