Design of filters in Matlab Simulink for reducing current harmonic distortion

The paper deals with design and implementation of three phase Electromagnetic Interference phenomenon. A Harmonic passive filter has been proposed for the three phase electrical power system network. The Matlab Simulink analysis of the three phase EMI harmonic filter system is incorporated. The design and implementation of the filters are illustrated, with specific attention to the strict requirements of the given power supply application. The passive EMI, Harmonic filter is an attractive topology of power system. Factors such as the absence of harmonic, increased power density, reduced size and weight and good power quality are fundamental aspects of good design considerations. An improved control structure is proposed. This structure employs simple R, L, C elements in order to attenuate or eliminate the undesired harmonic distortion in the output waveforms in the power network. Proposed system having RLC filter is analyzed and verified by simulation. The indepth analysis of the input and output waveforms clearly indicate the constraints that need to be satisfied for successful operation of the proposed filter.
