Abstract
For rectifier circuits with power factor correction, boost converters are generally used. As some restraints, it can be mentioned that the output voltage becomes limited to relatively higher voltage range. To expand the controlled range, buck-boostincluding like the Cuk converter types could be sometimes effective, because it has abilities to step-up and step-down over a widerange. This paper presents and discusses on a circuit configuration with power factor correction using buck boost converters. For the working process, various choppers having buck-boost function are compared and discussed with respect to some circuit characteristics and functions. Firstly, the paper discusses about the mechanisms of the power transmission and the characteristics based on the switching ripple and switching surge voltage of various converters. The distinction among buck boost converters are mentioned and discussed analytically. From such result, it can be seen that the canonical switching cell is mostly suitable for the single-phase power factor correction as buck boost chopper.
