dc.description.abstract	The demand for electrical energy has grown over the last few decades, putting a strain on our non-renewable energy resources. Thus, modern appliances’ design employs power electronics to consider issues like energy sustainability and energy savings. Widespread use of DC loads has made AC-DC converters essential. Conventional AC-DC converters consist of diodes for uncontrolled and thyristors for controlled power flow; therefore suffer from high Electromagnetic Interference (EMI), lower efficiency, decreased Power Factor (PF), and high Total Harmonic Distortion (THD). In this research work, A new single-phase AC-DC Buck-Boost converter is proposed comprising a compact passive LC3 configuration. The proposed converter can achieve higher efficiency while maintaining low THD and a close to unity input power factor. The converter circuit includes a bridge rectifier with an LC3 configuration and a conventional Buck-Boost converter. The inductance is kept above the critical value for the converter to operate in continuous conduction mode. Proportional-Integral (PI) based feedback control augmented the performance of the converter. The simulation result solidified the effectiveness of the proposed converter and its control system. The inclusion of a comparative analysis justifies the compatibility of the converter. The proposed converter achieved a 3% increase in efficiency, a 48% increase in power factor, and an overall 40% decrease in a total harmonic distortion compared to a conventional Buck-Boost circuit’s relevant performance.	en_US
