Analysis of Different Converters for Reduced Total Harmonic Distortion and Improved Power Factor

Abstract

Power electronics is a vast area in electrical engineering for research which includes different switching devices to control and switching of electrical machines and drives for their output, speed and torques etc. It has many applications in our everyday life such as motor drives, and power supplies for computer. The ‘current’ drawn by these devices is distorted so there is a necessity to use power factor correction converter. In this paper a comparative evaluation of different topologies of AC–DC converter is completed for Total Harmonic Distortion and enriched power factor. The model is simulated in MATLAB and their results are shown.
