静电放电模拟器辐照效应实验研究

对模拟器ESS - 2 0 0AX与NSG435的静电放电 (ESD)电流波形及其辐照效应实验进行了研究。实验结果表明 ,虽然两模拟器的放电电流波形均符合国际电工委员会IEC6 10 0 0 - 4- 2静电放电抗扰度实验标准 ,但进行辐照效应实验时 ,二者的测试结果并不一致。这主要是因为IEC标准只规定了放电电流的波形 ,而对模拟器放电枪的结构和外形未做出规定 ,使静电放电电磁场尤其是近区电磁场存在差异。要解决不同模拟器间测量结果的不一致性 ,IEC的相关标准除了规定放电电流的波形外 ,还应对放电电流的导数波形和相关的电磁场做出规定 ,尽量对放电枪的形状和结构给出统一的标准。

Study on the Radiation Effect Ex periments of ESD Simulators

In this paper, the performances of two types of ESD simulators (ESS-200AX made in Noiseken and NSG435 made in Schaffner ) are studied, and the radiation effect experiments of ESD EMP to single chip microcomputer(SCM) system are made.The experimental results show that the differences between two simulators will yield inconsistent test results though they both comply with IEC61000-4-2 ESD standard.To solve the inconsistence test results between different ESD simulators,besides ESD current waveform, the relevant IEC ESD standard should specify the discharge current derivative, related electromagnetic field in detail,and give unified specification for the constructions and configurations of ESD simulators as far as possible.
