High-Efficiency Single Phase Passive LC3 Component AC-DC Buck-Boost Converter

A new single-phase AC-DC Buck-Boost converter comprising a compact passive LC
³
configuration is proposed. The proposed converter can achieve higher efficiency while maintaining low Total Harmonic Distortion (THD) and a high input power factor (PF). The circuit contains bridge rectifier with an LC
³
configuration and a conventional Buck-Boost converter. The continuous conduction mode of the converter is contemplated. Closed-loop feedback control is used to enhance the performance parameters of the converter. To solidify the proposed converter and its control system, simulation results are shown. A comparative analysis is included for better perception of the converter.
