利用次级变压器串联均流的多路 LED 驱动器电路设计

摘要

提出了一种利用次级变压器串联的多路输出LED驱动器无源均流方案，给出了这种方案的工作原理和相应的设计。仿真分析表明：无论输出负载如何变化，三路的输出电流基本相同，确认了该方案是一种可行的无源均流方案。%A multi-output LED driver was presented with series second stage transformers and the working principle and the corresponding design parameters were highlighted for it .The simulation results showed that the each output current of three circuit is same basically ,no matter how the output load changes ,so the circuit design is feasible .
