Objective

Primary Objective: Modelling and simulation of Space Vector Pulse width
Modulation Voltage Source Inverter.

Secondary Objective: To creat alternating current waveforms and improve
the harmonic Performance.
Introduction

In future the generation of power depends upon the renewable energy.
Majority of renewable sources generates Dc power only.
So a converter is needed to convert the Dc to Ac called as inverter.

In order to vary the output voltage & frequency of the inverter most popular
PWM techniques are carrier based pwm & Space Vector Pulse Width
Modulation (SVPWM).

Approach
• The main focus of this paper is to implement simple
MATLAB/SIMULINK model.
• A model of a three-phase inverter is presented on the
basis of space vector representation .
• This is followed by the basic principle of SVPWM.
• Finally a MATLAB/SIMULINK model for the SVPWM is
presented.

• They show the modulation Index is higher for SVPWM as
compared to SPWM.
• For generating sine wave that provides a higher voltage to
the motor with lower total harmonic distortion.

Conclusion

A simple Matlab/Simulink model will be presented to implement
SVPWM for three-phase VSI.

By varying the magnitude of the input reference different
modulation index could be achieved.
