Learn fundamentals of harmonics and analyse each power electronics converters with MATLAB

Language: English

Instructor: Dr. Jignesh Makwana

Why this course?


Hello Everyone!

Wishing you a have happy and healthy life. Stay safe, stay blessed.

As I experienced that many  students found difficulties in understanding harmonics analysis and  total harmonics distortion. This is due to fact that most engineering  students are go through these important topic as a only part of their  other main subject like inverter or power quality analysis. That's why I  decided to built a course on particular topic "Harmonics Analysis &  THD". You may like to check the detail about this course.

This course explains harmonics,  requirement of fourier analysis & total harmonics distortion in  detail. Main aim of this course is to help student for clearing all  doubt about harmonics & its calculation methods.

First section covers method to  obtain THD and harmonics spectrum of different waveform. It explains  important of harmonics analysis and role of Fourier series in obtaining  harmonics spectrum.

Second includes MATLAB  programming & simulation tools to obtain THD as well as harmonics  spectrum of different waveform. It explains about using FFT toolbox and  THD function of MATLAB

Third section analyze harmonics  profile of all kinds of power electronics converters and explains how  it produces harmonics at different stages and effect how it affects load  side as well as supply side.

Course Summary

Who this course is for:

  • This  course is suitable for the diploma or degree students of electrical  engineering, power electronics engineering, electronics engineering  & power engineering.

  • This course is suitable for the person working with power electronics inverters or power quality related projects or industries.

  • This course is recommended for those who are going to use power quality analyser in their project.
