Design Of Led Driver Circuits With Single-Stage Pf Correction In DCM
LED driver with constant output current and power factor correction are presented in this paper. The non-isolated
Buck converters are used for the LED drivers, according to different operating mode of inductor current, power factor
correction is realized with Voltage Follower Control under DCM The designed circuits are verified by simulations of Orcad
PSpice software, and show that the proposed approaches achieved the goal of higher PF and constant output current.
