根据电子镇流器的基本电路原理，分析了各种照明灯个主要功能磁性器件（高频振荡器的逆变变压器和扼流器储能电感线圈）和辅助功能磁性器件（电网输入滤波器和各种电路滤波、磁性线圈）的实际工作状态和环境。探讨研究了对磁性材料性能和器件制作的要求．根据磁学理论，采用必要的工艺手段成功地研制了专用铁氧体磁性材料及器件，已广泛、可靠地应用于高品质、高稳定性、长寿命的电子镇流器节能灯中。
According to the basic circuit principle of electronic ballast, the paper analyzes the main function of various lighting devices (high frequency oscillator inverter transformer and choke coil inductor) and auxiliary functional magnetic devices (grid input filter and A variety of circuit filtering, magnetic coil) the actual working conditions and environment. Study on the performance of magnetic materials and device production requirements. According to the theory of magnetism, we have successfully developed special ferrite magnetic materials and devices by the necessary technological means, which have been widely and reliably applied to high-quality, high-stability and long-life electronic ballast energy-saving lamps.
