Abstract

This paper presents a single-stage active LED driver circuit with power factor correction, reduced power processing, and constant current output. This paper tries to achieve the advantages of many two-stage driver solutions, which offer power factor correction and constant output current regulation, with a single-stage approach. Input power distribution can be done without extra switches. With a simple ripple cancellation control logic, DC power and AC ripple power can be effectively matched, allowing electrolytic capacitors to be replaced with long-life film capacitors for increased LED driver lifespan. Reduced power processing design ensures that only a part of the input power is processed twice rather than the entire amount as in the case of two-stage driver circuits, thereby reducing the cost and size of the circuit. A single input, two-output power factor correction converter configuration has been discussed in this paper. On PSIM, a 30W simulation model is built and the results are validated.
