Critical Analysis of Power Factor Improvement of Single Phase AC/DC Converter by Passive/Active Filters

This paper provides a concise review of the most interesting passive and active filters of power factor correction, for single phase and low power applications. The increasing growth in the use of electronic equipment in recent years has resulted in a greater need to ensure that the line current harmonic content of any equipment connected to the ac mains is limited to meet regulatory standards. This requirement is usually satisfied by incorporating some form of Power Factor Correction (PFC) circuits to shape the input phase currents, so that they are sinusoidal in nature and are in phase with the input phase voltages. There are multiple solutions in which line current is sinusoidal. The major advantages and disadvantages are highlighted. Ms. Snehal B.
