Design and analysis of a modified multiport interleaved flyback converter operated photovoltaic shunt active power filter pv shapf

Abstract

In recent days an increased concern over the quality of the power newlinedelivered by the utility as it relates to the non-linear load. Non-linear loads newlinecause deviations from the ideal sinusoidal current and voltage waveforms. newlineNon-sinusoidal power line currents can lead to system noise and voltage newlineharmonics. Harmonic current in the power line can have a significant impact newlineon transformer function, medical apparatus, security systems, and control newlinesystems. Therefore, the quality of electricity for consumers has declined. newlineIndustrial users are concerned about a potential decline in power quality. newlinePower quality concerns are governed by standards set by IEEE and IEC. newlineThere has been a significant amount of research focused on enhancing newlineconsumer power quality due to the ongoing decline in power quality in the newlineelectrical power network. In recent times, several techniques have emerged to newlinereduce voltage distortions caused by non-linear loads. Passive and active newlinepower filters are enhanced to reduce current and voltage distortions. The newlineparameters of R, L, and C in a passive filter are determined by the specific newlineharmonic range that needs to be adjusted. The use of passive power filters newlineleads to the following issues: elimination of harmonics depends on the aging newlineof the passive components, use of L and C components may lead to resonance newlinein the power line, reconfiguration of filter needs complicated design and newlinecompensating only a specific harmonic order. newline
