摘要
本文介绍了荧光灯寿终(EOL)过程的仿真模型,对典型的镇流器拓扑以及14W T5灯管进行了仿真分析,并与实际的镇流器中的EOL电路参数作了比较,得出仿真模型与实际过程相一致的结论。同时,对于灯管端电压浮动的电路,从特定EOL检测点的检测电压显著的变化趋势说明EOL检测的合理性。
In this paper, an EOL lamp model is introduced, and is applied to T5 14W lamp, then the simulation results are compared with the tested ballast EOL parameters , a conclusion of consistency in the simulation and practical ballast is gained. Also, for those floating lamp topology circuits, the EOL sense point is quite reasonable due to the sharp increase of EOL test voltage as the EOL process gradually deepens.
