一种数字化单级电子镇流器的研究与设计

由于传统的双级电子镇流器线路较为复杂,成本也高,在推广使用中受到了一定的限制。设计一种体积小,成本低,高效节能的电子镇流器是目前"绿色照明"技术的一个发展方向。在系统分析了传统双级电子镇流器结构特性的基础上,提出一种数字化单级电子镇流器方案,采用单级方式同时控制镇流器输入功率因数校正和逆变输出。这样在保证可靠性和稳定性的前提下,可以降低镇流器的成本,同时为实现数字化照明控制奠定了基础。

Research and Design on a Digital Single-stage Electronic Ballast

Since traditional double-stage electronic ballasts have more complex circuits and higher costs,the popularization of these ballasts are limited.The design of an electronic ballast with small size,low cost and high luminous efficiency is a development tendency of the'green lighting'technologies.This paper presents one double-stage electronic ballast topology and one single-stage electronic ballast topology.Based on the structure analyses of traditional double-stage electronic bal-lasts,this paper presents a single-stage electronic ballast scheme,which integrates controls for both power factor correction and lamp supply at high frequency.As a result,the cost of an electronic ballast could be reduced together with its high re-liability and stability.Moreover,the ballast is a base of digital lighting control.
