High power factor integrated buck-boost flyback converter driving multiple outputs

2015 Online International Conference on Green Engineering and Technologies (IC-GET), 2015
This paper proposes an integrated single-stage ac-to-dc light-emitting-diode (LED) driver circuit. A buck-boost power factor (PF) corrector is integrated with a flyback converter. A recycling path is built to recover the inductive leakage energy. The proposed circuit provides high PF and low total harmonic distortion.
