金卤灯用低频方波电子镇流器的可靠性研究

Reliability Study on the Low-Frequency Square Wave Electronic Ballast for Metal Halide Lamps

针对金卤灯用低频方波电子镇流器存在偶发故障的现象,在开路启动、正常启动和热启动3个方面进行了深入研究。通过长时间实验寻找故障,分析原因,改进设计,极大地提高了电子镇流器的可靠性。

Aiming at the occasional failure phenomenon of low-frequency square wave electronic ballast used for metal halide lamps, the author made a deep research on the open start, normal start and hot start. By conducting prolonged experiment to find fault, to analyze the reasons and improve the design, the reliability of electronic ballasts was greatly improved.
