摘要

本文介绍了静电放电(ESD)产生的电流和电磁场的时域测量。使用无源近场探头在时域测量距离静电放电几厘米的电磁场。通过FFT将时域信号转换为频域信号，并应用天线校正因子。静电放电电流由静电发生器产生。典型的ESD电流为10a，上升时间为25ns，在距离ESD 10mm处可产生70 /spl mu/T的磁场，在距离ESD 30mm处可产生6kv /m的电场。研究了电磁场随放电距离的变化规律。

Time varying electromagnetic fields generated by electrostatic discharges

This paper presents the time domain measurements of current and electromagnetic fields generated by electrostatic discharges (ESD). Electromagnetic fields a few centimetres away from the ESD were measured in time domain using passive near field probes. The time domain signals were converted into the frequency domain by FFT, and antenna correction factors were applied. The ESD current was generated by an ESD generator. A typical ESD current of 10 A with 25 ns rise time can create a magnetic field of the order of 70 /spl mu/T at a distance of 10 mm from the ESD and an electric field of the order of 6 kV/m at a distance of 30 mm from the ESD. The variation of these electromagnetic fields with distance from the discharge is also investigated.
