高性能电子镇流器的电路设计.doc

摘要 目前世界上各发达国家和有关发展中国家纷纷制订了“绿色照明计划”，我国也于1997年10月1日正式启动了“绿色照明工程”。这是我国照明技术领域内的一项重大决策和举措，必将我国的能源、电光源和照明技术，甚至环境保护等各个领域产生巨大的影响，对确保我国国民经济可持续发展具有非常重大的意义。 电子镇流器采用高频开关变换电子技术的方法实现负阻性气体放电灯的镇流，具有无频闪、效率高、体积小、重量轻、可调光、不使用大量铜材和硅钢材料、适应供电电压范围宽和节能灯一系列优点，所以自20世纪70年代问世以来，受到了用户的欢迎。 据统计，世界上照明用电占了世界上总发电量的1/4如仅将现用的200亿只灯泡中的50亿只换成节能的电子镇流器灯泡，每年就可节省约200GW的电能。由于高频交流电子镇流器的节能和巨大的市场潜力，进入20世纪90年代后，各种负阻性气体放电灯采用高效、节能的高频交流电子镇流器已是大势所趋，形成了一个“绿色照明”的新兴产业。可以说，绿色照明工程是21世纪最具魅力的产业之一，并已成为各国政府大力推行的一项基本国策。用气体放电灯（低压放电灯——荧光灯;高压放电灯——汞弧灯、高压钠灯、金属卤化物灯等）取代耗电多、效率低的白炽灯渐成大趋势。 关键词：绿色照明、节能、高频交流电子镇流器 Abstract The worlds developed countries and the developing countries have drawn up a Green Lighting Plan, China is also in October 1, 1997 officially launched the Green Lights Program. This is the field of lighting technology as one of the major policy decisions and initiatives, will Chinas energy, power source and lighting technology, environmental protection and other fields and even have an enormous impact, to ensure sustainable development of Chinas national economy has a very significant significance. Electronic ballast using high frequency switching method of transformation of electronic technology to achieve negative resistance of the gas discharge lamp ballast with no stroboscopic, high efficiency, small size, light weight, adjustable light, do not use a large number of copper and silicon steel materials to adapt to a wide range of supply voltage and energy-saving lamps are a number of advantages, so since the advent of the 20th century, since the 70s, has been welcomed by users. According to statistics, the worlds electricity lighting up the worlds total generating capacity of 1 / 4, such as is used in only 20 billion light bulbs in the five billion into energy-saving electronic ballast bulb, each year would save about 200GW power. As a result of the exchange of high-frequency electronic ballasts for energy saving and huge market potential, the beginning of the 20th century, after the 90s, all kinds of negative res
