Abstract :
This paper presents a single-stage flyback power-factor-correction (PFC) front-end for high-brightness light-emitting-diode (HB LED) applications. The proposed PFC front-end circuit combines the PFC stage and the dc/dc stage into a single stage. Experimental results obtained on a 78-W (24V/ 3.25-A) prototype circuit show that at VIN = 110 Vac, the proposed PFC front-end for HB LED applications can achieve an efficiency of 87.5%, a power factor of 0.98, and a total harmonic distortion (THD) of 14% with line-current sharmonics that meet the IEC 61000-3-2 Class C standard.
