This paper presents a single-stage power factor correction flyback converter without the electrolytic capacitor. To reduce the large 120[Hz] ripples on the output because of electrolytic capacitor replacing with film capacitor, the LCfilter is proposed. The current programmed control is used to maintain constant current of LED lighting and power factor correction. To verify the performance, the proposed circuit is confirmed by simulation
