LED Driving Topology for Efficiency Improvement of Solid state Luminaries Using Isolated Buck Converter

LED lights, powered by an isolated buck converter, are seen as a possible replacement for incandescent bulbs due to their great efficiency and extended lifespan. Since the LED VI properties are temperature dependent, it is important to create energy-efficient LED driver topologies that can provide constant current control. Focusing on power density, multi-string operation, renewable energy usage, soft switching, optical wireless communication, dependability, and size utilising an isolated buck converter, this research covers the main aspects of several LED driver topologies. These topologies are compared and contrasted in terms of efficiency, power output, number of components, galvanic isolation, and switching frequency of the converter. This research examines strategies for enhancing efficiency while focusing on the many factors of predicting the lifespan and reliability of LED drivers. The article will look into the future and make some educated guesses on where certain technologies, such as programmable LED lamp drivers, smart LED lighting for the internet of things (IoT), and wide band gap power semiconductor materials, are headed. Researchers, designers, and engineers may greatly benefit from this in-depth analysis of the technologies available to them as they work to determine the optimal topology.
