The conventional boost converters can generally be used for rectifier circuits with power factor correction, and as a result the output voltage becomes limited. Tb expand the controlled voltage range, buck-boost or Ćuk converter types should be utilized. This paper discusses a circuit configuration for power factor correction. Single-phase power factor correction using a buck boost converter can control the output voltage over a wide range because it has the ability to step-up and step-down the output voltage. Firstly, this paper compares the mechanisms o f the power transmission and the characteristics based on the voltage and the current ripple. Secondly, these converters are applied to the single-phase power factor correction. Among them, we can see that CSC (Canonical switching cell) converter is the best choice with regard to input current ripple and current distortion. It is shown that this converter is suitable for power factor correction.
