摘要
随着高速数字印刷电路、无线射频识别系统以及射频器件的迅速发展,电子设备产生的大量电磁抗干扰的情况,严重影响其它设备的正常运行,甚至出现误操作等问题.国家食品药品监督管理局也正式公布医用设备电磁兼容标准YY 0505-2012,并于2014年1月1日正式实施,医疗产品的EFT(电快速脉冲群)抗干扰能力成为关键之一.本文研究了EFT干扰信号的能量分布以及单个元件的寄生参数消除方法,并提出了提高EFT滤波器在较高频段的滤波特性的方法,最后以实验论证.
With the rapid development of high-speed digital printed circuit,radio frequency identification systems,andRF devices,a lot of electromagnetic interference generated by electronic equipment cases have serious effect on the nor-mal operation of other equipment,or even misuse and other problems. Office of the State Food and Drug Administrationofficially determines electromagnetic compatibility standards for medical equipment YY 0505-2012 which was formallyimplemented on January 1,2014,so medical products,anti-jamming capability for EFT（Electrical Fast Transient）hasbecome one of the key problem. This paper studies the energy distribution of EFT interference signal and the method ofCancellation of Parasitic Parameters for single element,a method is proposed to improve the filter characteristic of EFTfilter at higher frequency and finally an experiment is made to prove the method.
