Linear regulator based compact LED driver for DC distributed lighting system

Abstract

This paper presents a linear regulator based LED driver, suitable for DC power distribution architectures. The steady state model and small signal analysis of the proposed circuit is presented. The compensator design and functional verification of the proposed driver through simulation using SIMetrix/SIMPLIS software are presented in this paper. The performance of the proposed driver, with compensator, is experimentally verified on a 20W LED string.
