Power Factor Correction using Continuous Conduction Mode based Bridgeless SEPIC Converter for Improved THD and Voltage Regulation

In this presented paper the operation of Bridgeless SEPIC (Single ended primary inductance) for PFC is compared with conventional full bridge SEPIC topology, this presented converter for PFC has less active and passive component count, low conduction loss and less component are conducting during each mode of operation. The topology is designed in CCM (continuous mode) to attain high power factor, low THD in input current and improved voltage regulation. The detailed analysis of the presented model is validated through MATLAB Simulink.
