| 摘 要： | 无人机交换机芯片易被静电放电(ESD)电磁脉冲损坏，严重影响无人机数据链正常通信。针对此问题，通过搭建人体-金属ESD电路模型并进行仿真分析，发现所选用的TVS防护器件对15 kV等级的ESD防护效果显著。分别对加装TVS防护器件前后的收发信机电路进行了ESD电磁脉冲抗扰度对比试验。试验结果表明，加装防护器件后的电路对ESD电磁脉冲的防护能力最大提升7.4倍。

| Abstract: | The fact that switch chip in the UAV is easily damaged by the ESD electromagnetic pulse severely affects the normal communication of UAV data link. To solve the problem, this paper presents an approach by building human body-metal ESD circuit model and proceeds with a simulation analysis. It is shown that the protection effect of the chosen TVS device is significant under the 15 kV level of ESD. A comparison test of immunity to ESD electromagnetic pulse was carried out for the transceiver circuit before and after the installation of TVS protection devices respectively. The test shows that when the protection devices was installed in the circuit, the protection capacity against ESD electromagnetic pulse was maximally enhanced 7.4 times that before the installation. |
