Abstract
This paper presents the idea of utilizing large voltage ripple with small capacitance for energy storage in LED circuit, instead of large capacitance with small voltage ripple. A typical Single-Stage PFC converter with small capacitor is adopted. The presented converter has high input power factor and low output voltage ripple at the same time. Calculation method of main parameters are derived. In order to verify the method, a prototype with 198∼265V AC input/ 24V DC output/60W is designed. The experimental results show that the design method is feasible.
