摘要
电子镇流器就等于一个高频电源,而且频率越高,节能越有效果。高频电源对所有组成元器件有特定的要求,磁性器件及器件所用材料的选择是关键之一。研究了电子镇流器中不同频率特性的脉冲变压器磁芯对传导干扰的影响问题,实验数据发现脉冲变压器磁芯电感值随频率变化,对电子镇流器的传导频谱的影响明显。实验结果对于电子镇流器设计和磁芯材料研制具有参考价值。
Having studied the influence on conducting interference of magnetism core of pulse transformer at different frequency characteristic in the electronic ballast, the experimental data finds that the inductance value of the pulse transformer magnetism core varies with frequency, and strongly influence the conducting spectral on electronic ballast. The results are worth consulting to the design of the electronic ballast and research of the magnetism core materials.
