摘要
关于荧光灯等气体放电灯的镇流器的镇流原理,一般都归结为在灯管电路中串联一个足够大的阻抗来抑制灯管电流的过度变化,即所谓串联阻抗镇流。本文提出了变阻抗镇流的概念。通过分析,说明在工频工作的呈容性阻抗的LC镇流器与高频工作的电子镇流器电路中,变阻抗镇流原理起了重要作用。可以运用变阻抗镇流原理来拓宽电子镇流器电路设计的思路。
In this paper provides the concept of ostatic variable - ballast. Through the analysis of the frequency was the work of the capacitive impedance of the LC ballast with the work of the high - frequency electronic ballast circuit,the impedance change ballast principle played an important role. We can change the principle of ostatic valiable - ballast to expand the flow Ballast principles of design ideas.
