【摘要】 由于不可再生能源可预见性的短缺,节能已经成为一个全球性话题,绿色照明正引起越来越多的关注。作为一种高效、显色性好、长寿命的新型电光源高强度气体放电灯(HID)在绿色照明工程中扮演了重要的角色,特别是金属卤化物灯同时具备上述优点而被称为最理想的光源,在泛光照明中逐渐得到广泛的应用。与之配套的电子镇流器由于其节能、轻便等一系列优点将替代传统的电感式镇流器,成为了研究热点。 论文首先简要介绍了电光源的发展及分类,回顾了镇流器的发展过程,介绍了气体放电灯的基本特性和镇流器的基本工作原理,并对电感式镇流器和电子镇流器进行了简单的实验对比,分析了电子镇流器的优越性。 随后,在分析HID灯用电子镇流器的基本功能以及灯的启动特性的基础上,分别介绍了电子镇流器的几种拓扑结构、功率控制方法和启动电路,并对他们进行了分析和比较,找到其中比较实用、方便的方法。 本文第五章详细介绍了70W陶瓷金属卤化物灯的三级式和两级式电子镇流器的设计过程,并对它们进行了实验研究,给出了实验结果,并进行了分析。文章最后给出了结论。更多还原

【Abstract】 Because of the shortage of non-renewable energy, energy saving has become a worldwide topic. Being part of it, green lighting projects are attracting more and more attention. The High-Intensity-Discharge Lamps (HID) are notable for their high luminous efficacy, good color rendering, and long life. Metal halide lamps (MHL) have the best combination of the above properties and are considered the most ideal light sources. Therefore the development of the drive circuit of the lamp, namely ballast has become an important research point. Because of the excellence in energy saving, light weight, etc., electronic ballast will gradually take the place of traditional electromagnetic (EM) ballast.At the beginning of the thesis, the development process of ballast is presented and the operation principles of discharge lamp as well as the ballast are introduced. Experimental comparison between EM ballast and electronic ballast is conducted to analyze the advantage and disadvantage of each of them.Based on the basic functions of electronic ballast and the start-up characteristics of the HID lamps, different topologies, power control methods and start-up circuits were introduced one by one. And comparative results were given out in the last of each chapter.Finally the design process of a three -stage ballast and a two-stage ballast for 70W ceramic metal halide lamp was presented. Experimental results were given out to verify the theory before.更多还原
