Abstract: This paper analysis with PFC Cuk converter fed LED drive to overcome the power factor problems. The proposed circuit topology consists of diode bridge rectifier and Cuk converter. Cuk converter is operated to work under CCM mode. This combination of DBR and PFC converter is used to feed a LED drive. This converter is simulated in MATLAB software. This Cuk converter provides better results such as unity power factor and low current harmonic distortion with fuzzy logic control and hysteresis control.

Keywords: Power factor, THD, Cuk converter, CCM, Fuzzy logic control
