Abstract

This project is focus in the creating e-learning tools of a Harmonics of Power Electronics. E-learning is a type of education in interactive way by using the computer as a medium of learning. E-learning is used interchangeably in a wide variety of contexts. Harmonics is the form of the frequencies that is integer multiple of the fundamental frequency. To analyze harmonics, Fourier series is applied. Fourier series is the decomposition of a function in terms of sinusoidal functions (called basis functions) of different frequencies that can be recombined to obtain the original function. In other word, Fourier series is a made up of infinite sum of sines and cosines with frequencies that are multiple of the fundamental frequency. There are four types of harmonics wave in this tool that is sines wave, square wave, triangular wave and sawtooth wave. This project has simulation of harmonics to help student in better understanding of harmonics and Fourier series. The simulations are is the forming of triangle wave, square wave and sawtooth wave from basic sine wave. This tool also included with even and odd function simulation. Exercises are provided for student to test their understanding the basic concept of harmonics.
