Both electric utilities and end users of electric power are becoming increasingly concerned about the quality of electric power. It is an umbrella concept for a multitude of individual types of power system disturbances. One such major concern is the harmonics which is made the focus of study in this work. When electronic power converters first became commonplace in the late 1970s, many utility engineers became quite concerned about the ability of the power system to accommodate the harmonic distortion. Harmonics problems counter many of the conventional rules of power system design and operation that consider only the fundamental frequency. Therefore, the engineer is faced with unfamiliar phenomena that require unfamiliar tools to analyze and unfamiliar equipment to solve. This thesis is basically concerned with the Analysis and Mitigation of Harmonics generated by Power Electronic Converters. MATLAB/SIMULINK has been employed for presenting the simulation results because it is well established and recognized simulation software for the power system. Next, the designing of Passive Filter is carried out after a literature review and have been applied to the converters for harmonics mitigation. In the future, we would proceed to work on Active Filters for Harmonics Mitigation. One of such problem is generation of current and voltage harmonics causing distortion of load waveform, voltage fluctuation, voltage dip, heating of equipment etc. Also presence of non-linear loads such as UPS, SMPS, speed drives etc. causes the generation of current harmonics in power system. They draw reactive power components of current from the AC mains, hence causing disturbance in supply current waveform. Thus to avoid the consequences of harmonics we have to compensate the harmonic component in power utility system.
