高频电子镇流器的频率分析与设计

从荧光灯的固有频率变化曲线特性出发，分析了负载对变频输入的响应以及灯管主要频率点与输出回路参数的相互关系，闸述了电子镇流器中电感、电容参数的选择如何与灯管的电气特性进行较好的匹配，利用BL8301芯片进行了电路设计。实验结果表明，灯管电气特性频率与电子镇流器参数相匹配的思路有利于延长灯管寿命。

Frequency Analysis and Design of High-frenquency Electronic Ballast

The response of loads to frequency variation of input and connection between main frequency of lamp and parameters of output circuits is analyzed from intrinsic frequency variation curve of fluorescent lamp in this paper, and we get a way how to select the parameters of inductance and capacitance to match electric proper- ty of lamp. The result of experiments shows that the idea to use BL8301 to make electric property frequency of lamp suitable for electronic ballast is helpful to longer the span of life of lamp.
