Design and Simulation of an Efficient LED Driver for Street Light Application
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 4
Abstract
This paper presents the multistage high brightness (HB) LED driver for the application of street lighting. This paper focus on the reliability because the LED’s may last for greater than 50,000 hours but the drivers may not; hence the driver design has to be such that they outdo the life of LED’s .The existing two stage HB LED driver is modified here as three stage (multistage) to improve its reliability as well as the performance. The three stages are PFC boost converter, asymmetric half bridge converter and a current controlled buck converter. Each stage performs separate tasks to improve the efficiency of the driver circuit. The simulation of three stage HB-LED driver was done and it is presented in this paper using MATLAB software.
