Abstract: The use of electronic equipment has increased in last few years. Therefore there is an immense need to ensure that the line current harmonics of any equipment connected to AC main line is limited to comply the regulatory standard. This requirement is satisfied by introducing some form of Power factor Correction (PFC) techniques to make the input current sinusoidal and reduce the harmonics. In this paper, a systematic review of power factor correction (PFC) boost rectifiers is presented. Performance comparison of conventional PFC boost rectifier at different duty ratio and voltages are shown and their efficiency is calculated.
