摘要
研究了静电放电抗扰度试验,发现满足IEC6100042标准规定的不同的ESD模拟器对同一试验对象所得实验结果不同;放电电流导数和模拟器内部开关继电器的电磁辐射对实验结果有很大影响。分析认为,造成上述问题的原因之一是IEC标准对电流校验波形的规定不够严格,未具体规定空气放电方式,使实验结果与实际不符。最后建议标准应规定电流导数波形参数,限制电流波形的振荡;必要时应对模拟器开关采取屏蔽措施,限制模拟器开关的辐射;应进一步研究空气放电的特点,建立符合实际应用需要的实验平台。
A series of experimental research are accomplished in test method and test setup of ESD immunity test stipulated in IEC61000-4-2. It is found that different ESD simulators may yield inconsistent sensitivity test results for a certain EUT (equipment under test), though they both meet IEC61000-4-2 standard. The experimental result is greatly influenced by the lead number of ESD current and the electromagnetic radiation of switching relay inside ESD simulators. So one of the reasons causing the above problems is that current waveform is not strictly defined in IEC standard. And this IEC standard gives no definition for the air discharge, causing the unconformity between experiment result and reality. It is suggested that the IEC standard should define the parameters of lead number of ESD current waveform, restrict the oscillation of the current waveform, limit the radiation field of the simulators switch and shield the simulators switch if necessary. Also, further research on the characteristics of air discharge is performed to establish a test platform that meets the needs in practice.
