Abstract :
A closed loop control of PFC Bridgeless SEPIC converter is introduced in this paper for using it as a low voltage switched mode power supply for LED lightning applications. The PFC bridgeless SEPIC converter discussed here has PFC capability and low conduction losses. The discussed control scheme make use of a voltage control strategy. It retains all features of the bridgeless SEPIC converter moreover; it helps in achieving load regulation. The simulation is done using MATLAB. Simulation results of converter are provided for verifying the control scheme.
