Power Quality Enhancement in Single Stage Non-inverted Output Bridgeless Buck–Boost Converter

This research manuscript proposes a bridgeless single phase buck–boost power factor correction converter providing non-inverted DC load voltage. Proposed topology has two power switches in the current path over every switching period, and moreover, this topology does not have bridge rectifier at the input side. Therefore, it leads to improved thermal management and reduced conduction losses. This further increases the efficiency of the system. The suggested converter offers unity input as it is operated in discontinuous conduction mode. Harmonic content in supply current is greatly reduced improving the power quality indices to the recommended standard. In this manuscript, performance analysis of the proposed converter is observed, and its implementation is compared with standard buck–boost converter.
