中文摘要：

该文介绍了一种电子镇流器的有源功率因数校正技术,利用L6561芯片实现有源功率因素校正控制调节,并对L6561的APFC电路做了详细分析。应用在2×26W荧光灯中,使用UI2000电子镇流器综合测试仪对荧光灯进行测试,结果表明,电子镇流器的功率因数达到0.990以上,总谐波畸变在10%以下。

英文摘要：

This paper introduces the active power factor correction（APFC）of electronic ballast（EB）, analyses the elements and function of the APFC part which makes use the IC of L6561. Applies to the fluorescence lamp of 2 × 26W, then tested by the machine of EB synthesis test called UI2000, the test indicates that the PF of the EB will be higher than 0.99, the total harmonic distortion（THD）will be lower than 10%.
