The Light Emitting Diodes (LEDs) are gaining more importance in several lighting applications due to their advantages, such as high efficiency, long life, and environment friendliness, over conventional lighting sources. The driver circuit is a significant component in an LED lighting system to provide regulated power to the lamp. Numerous, DC-DC converter topologies have been proposed for LED lighting applications. Under which low- and medium-power lighting applications such as domestic lighting, traffic lighting, and decorative lighting, non-isolated driver circuits are more beneficial. However, in high-power applications such as street lighting and industrial lighting, isolated and soft switching converters are mostly used as LED driver circuits. Due to high-power capability, reduced switching losses, less component count, high frequency of operation, and high efficiency, soft switching converters are drawing more attention in high-power applications. This paper presents a comparative analysis of resonant LED driver topologies proposed for multiple load lighting applications. Simulations of a few full bridge LED driver topologies have been carried out using MATLAB/Simulink environment. Various performance parameters are evaluated, and finally, conclusions are drawn.
