An investigation of harmonic losses from personal computer due to type of voltage source

Abstract

This project is about investigating harmonics distortion caused by the type of voltage source to personal computer (laptop). The voltage sources for this project are sine wave, square wave, triangle wave and combination of harmonic 3rd and 5th. The load that has been used for this project is Computer which will draw non-sinusoidal current with odd number of harmonics more significantly. Harmonic distortion from the load will be measured due to multiple types of voltage source waveforms and as the solution the harmonic filter will be designed to reduce harmonic distortion and improve the power factor. Comparison value with harmonic filter and without harmonic filter will be shown to prove that harmonic value will decrease and power factor will be increase.
