Abstract :
This paper proposes a novel single-stage LLC resonant ac-dc converter with power factor correction feature. The proposed circuit is the integration of a buck-boost type power factor corrector and an LLC resonant dc-dc converter. The proposed single-stage converter which has power factor correction and output voltage regulation features can simplify circuit complexity, reduce cost, and increase system reliability over conventional two-stage systems. Experimental results of a 100 W prototype are used to verify the feasibility and validity of the theoretical predictions.
