| 摘 要： | 本通过分析电子镇流器的基本线路结构，针对电子镇流器使用中出现的“共态导通”、启动速度过快导致灯管早期失效以及功率因数过低对电网造成污染等问题，提出了相关的电路改进措施；并强调了在电子镇流器中为降低功率开关管的自身功率，除了电流增益参数须配对以外，还必须对开关时间参数进行匹配。

| Abstract: | Based on the analysis of the basic circuit structure of electronic ballast, directed at the problems such as the common\|state conduction arising in the use of electronic ballast, the earlier deactivation of light tube caused by over\|fast starting speed, and the pollution to the power network brought about by the lower power, this paper presents the relevant circuit measures for improvement. And in the meantime, it emphasizes the matching of time parameter of switch in order to lower the power of power switching transistor, in addition to the matching of gain parameter of current. |
