A new single-stage single-switch power-factor-corrector using magnetic feedback

This paper presents a new single-stage single-switch PFC using magnetic feedback to reduce the input current harmonic distortion and limit the voltage stress across the bulk capacitor. This topology uses a new magnetic feedback witch changes from one mode to another smoothly so the low frequency harmonic distortion will decrees significantly. The converter different modes are explained and results are verified with simulation and experimental results.
