چکیده
Abstract The photoelectric properties of LED are affected by driving current and ambient temperature. To solve the problem light wane caused excessive overheating, LLC resonant converter with soft switching was chosen as main topology, improving power efficiency, reducing heat driver. Firstly, soft-switching conditions analyzed, constraint equation is obtained. Then, an improved particle swarm optimization algorithm proposed to optimize parameters. weight particles dynamically adaptively changed balance global local performance particles. Finally, controller designed realize constant current. This design improves efficiency At same time, effectively suppressed stable output current, rationality selected parameters verified simulation experiment.
