资料介绍

为实现多基色LED光源的自稳定和智能调光,提出一种基于有源均流技术的单电感多路输出LED驱动电路.与现有均流方法相比,该驱动电路只使用一个磁性元件,可扩展驱动任意通道的LED负载,而且智能化调节程度高.本文对该驱动的均流原理和控制方法进行了分析,并通过PSIM仿真软件和实测结果验证了电路性能,该驱动电路可实现多基色LED光源的自稳定智能调光.

In order to realize the self-stabilization and intelligent dimming of the multi-color LED light source, a single inductor multi-output LED driver based on active current sharing technology is proposed.Compared with the existing balancing method, the proposed driver uses only one magnetic component, which can drive odd or even channels' LED load, and the intelligent regulation degree is high.In this paper, the principle and control method of the driver are analyzed, and the performance of the circuit is verified by the PSIM simulation software and the measured results, the driving circuit can realize self-stabilized intelligent dimming of multi-color LED light source.
