摘要
以基于恩智浦半桥驱动IC UBA2211设计的荧光灯电子镇流器为例,针对电路中存在的传导干扰,探讨了不同的滤波方法。在电路的电源入口处采取滤波技术可对电路的EMI进行有效抑制,测试结果表明电路的传导干扰达到了国际的EMC标准限值。
Taking fluoresc an example, several circuit. Adding the show that the eondu standard. ent lamp electronic ballast designed based on NXP＇s half-bridge driver IC UBA2211 as filter methods are discussed for suppressing the conducted interference presenting in the filter in tile power port can eftetively suppress the EMI interference. The test results eted interference in circuit does not beyond the limit value of the international EMC
