摘要 这里介绍了一种适用于发光二极管(LED)驱动的Buck-PFC电路的电感优化设计的理论方法,建立了基于BCM模式下电路的损耗模型,给出频率的边界情况,通过仿真和样机实验,得出理论研究、仿真分析与实验结果具有高度一致性,在工程实践上,为LED电源设计中电感优化设计和效率提升提供理论依据。 Based on the efficiency model of the Buck power factor correction （Buck-PFC） light emitting diode （LED） driver circuit, the theory analysis of the inductor optimal design is proposed, where the inductor operates in boundary conduction mode （BCM）.Considering about the frequency performance and electromagnetic interference （EMI） of the driver circuit,the boundary.condition of the frequency is given.The simulation and experiment results are presented to verify the theory analysis of the inductor.
