摘　　要：电子镇流器是一种特殊的开关电源,应用非常广泛,普遍应用于日光灯,节能灯,HID灯等大量的日常照明设备中。为了使我们的电子镇流器符合国家标准GB17743-1999,对应的国际标准是CISPR15-1995,针对目前国内大量的电子镇流器不能达到国家或国际的EMC/EMI标准的突出问题,利用我们的工程经验和电磁兼容理论,采用双π型滤波器,专门研究设计出一种更加经济且小型化的EMI滤波器,使得该镇流器达到国家标准GB17743-1999,使之具有极大的现实意义和应用价值。Electronic ballast belongs to one special kind of switching power supply. It is commonly used in fluorescent lamp,energy saving lamp, HID lamp and so on. It is very popular in usual lamp devices. As there are so many electronic ballasts that are not compatible with the National Safety Standard of China, we design a smaller, low-cost filter by double π style with our engineer experience and theoretically knowledge of EMC to make this kind of ballasts conform to the safety rules. The standard＇s number GB 17743-1999 equal is to the international standard CISPR 15-1995. The EMI filter will be valuable to be used in usual lamp devices.
