Implementation of selective harmonics elimination for single phase inverter using arduino and simulink matlab model

Abstract EN

This paper presents Arduino controller implementation and Simulink model inMATLAB to eliminate a selected number of harmonics in a single phase inverter.

A MATLAB code is written to solve the nonlinear trigonometric that arises in theFourier analysis of the output of the inverter.

Newton's Raphson method is adoptedto find the triggering angles for the four electronic switches in the inverter.

Allpossible combinations of these triggering instants are then computed for periodof one cycle.

To validate the model a practical set using Arduino controller isimplemented.

Frequency spectrums of the output of the inverter for both theSimulink model and the practical set are shown for the elimination of certainselected harmonics.

Any other selected harmonics can be eliminated using theproposed model.
