Explore how to analyze a notched waveform and reduce total harmonic distortion using MATLAB, by selecting alpha angles to eliminate specific harmonics and shape the waveform toward the fundamental.
Understand how harmonics in Inverter output creates trouble to the Induction motor running on drive VFD. Understand the role of harmonics in cogging and crawling effect of Induction Motor.
This lecture analyzes harmonics caused by regulators and ac regulators, showing how voltage control distorts current and degrades induction motor performance, and discusses chopper solutions to reduce harmonic content.
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.
Introduction:
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.
