摘　　要：详细分析了有源电力滤波器和电子镇流器的工作原理,针对电子镇流器的谐波问题,比较了采用PFC(Power Factor Correction)和APF各自的优缺点,同时分析了其它检测算法的利弊,提出了一种基于自适应算法的有源电力滤波器,其检测系统闭环、检测精度高、有自适应能力。通过在PSIM软件上仿真,验证了该方案不但能满足功率因素的要求,还能有效滤除谐波,降低对电网的不良影响。The principle of Active Power Filter （ APF ） and Electronic Ballast are analyzed in detail. Considering the harmonics of electronic ballast, their advantages and disadvantages for the PFC （ Power Factor Correction ） and APF are compared respectively. Furthermore, the pros and cons of other detection algorithms are analyzed. An APF based on adaptive algorithm is presented. The closed loop detecting system has a high detection precision, and the adaptive capacity. By the PSIM simulation software, verify that the program not only meets the requirements of the power factor, but also can effectively eliminate harmonics and reduce the adverse impact on the power grid.
