Interleaved boost-flyback converter with boundary conduction mode for power factor correction

2011 6th IEEE Conference on Industrial Electronics and Applications, 2011
This paper presents a new interleaved pulse-width modulation (PWM) boost-flyback converter to achieve power factor correction (PFC) and regulate DC bus voltage. The adopted boost-flyback converter has a high voltage conversion ratio to overcome the limit of conventional boost or buck-boost converter with narrow turn-off period.
