摘要：高压钠(HPS)灯是高强度放电灯的一种，因其具有高光效(8(Z4()hn/W)、省电、寿第长和透 雾性强爭优点，而被广泛应用。传统的电感式缜流器存在功率因数低和自身损耗大的缺点，而且对电 网电压沈动的适应能力不强，所以研制性价比较离的电子镇流器取代电感式镇流器是大势所趋。目 前，离压钠灯电子镇流器大多都是高频电子镇流器，在高频状态下，高压钠灯容易熄弧，存在声共振 问题。文章利用可变频脉冲信号产生器设计的离压钠灯电子缜流器较好地避免了声共振问题，加上 异常工作状态保护电路，使电子镇流器的性能显著提高。

Abstract: The high-pressure sodium (HPS) lamps are one kind of high intensity discharging lamp. They are widely used because they possess such advantages as high light efficiency (80-140 lm/W)r energy-savingr Iong life and strong power to penetrate the fogr etc. Traditional inductive ballasts have many shortcomings. Not only is the power factor low and wastage great but also the ability to adapt to the grid voltage fluctuation is not strong. Therefore, the research of electronic ballasts which have a higher cost-effective to replace inductive ballasts is the general trend. Currently, most of the HPS lamp electronic ballasts are high frequency
