The devices generally used in industrial, commercial and residential applications need toundergo power electronics converter for their proper functioning. They are connected to the gridcomprising of non-linear loads and thus have non-linear input characteristics, which results inproduced distortion input line current. Also, current comprising of frequency components at multiplesof line frequency is observed which lead to line harmonics. Due to the increasing demand of thesedevices, the line current harmonics pose a major problem by degrading the power factor of the systemthus affecting the performance of the devices. Hence there is a need to reduce the line currentharmonics so as to improve the power factor of the system. This has led to designing of Power FactorCorrection circuits. Rectifier is commonly used for AC-DC power conversion. As mention above thatwith the help of rectifier the input line current waveform will distorted. And leads to insert lineharmonics, and result of that poor power quality and poor power factor. Now, to improve power factorin that type conversion is to introduced an input current wave shaper between rectifier and load
