| Abstract | This Abstract proposes a high brightness, high efficiency, dimmable LED driver based on linear current regulator technology for DC grid distribution systems. The proposed driver has excellent characteristics like the highest lumen per watt, long lifetime, high reliability, compact, low cost, both environmental and user-friendly which makes it suitable for lighting applications. Steady-state and small-signal models of the proposed driver is performed which helps in minimizing ground current and accurate compensator design, respectively. These two modeling approaches result in the optimization of both the footprint and cost of the driver. The performance of the proposed Experimental prototype of the 20W driver developed to validate the performance at different dimming levels and achieves maximum efficiency of 97%. the applications of the proposed converter are: dimmable home lighting system, advertisement boards and hoardings, industrial lighting systems, road transport indication lamps, indoor and outdoor stadium lighting, automatic street lighting, decorative systems, health appliances and auditoriums and many more |
