摘要

提出了一种实验发生器，它可以产生一个阻尼正弦电流波形，用于有意电磁干扰(IEMI)的研究。该发电机基于充气平行板传输线，能够产生IEC61000-4-36标准熟练技术范畴的电场强度。与此类别中可用的发生器相比，所提出的发生器在控制脉冲幅度方面更简单，但更通用;它可以在其板之间产生从0到~ 230 kV/m的场强，充电电压为34 kV。也可以通过改变传输线的长度来改变工作频率。为设置创建电路模型以模拟电流波形。模拟的电流波形与实测的电流波形吻合较好。

A New Tunable Damped Sine-like Waveform Generator For IEMI Applications

An experimental generator is presented, which can produce a damped sine-like current waveform for intentional electromagnetic interference (IEMI) studies. The generator is based on an air-filled parallel plate transmission line and is capable of generating an electric field strength in the skilled technical category of IEC61000-4-36 standard. Compared to available generators in this category, the proposed generator is simpler yet more versatile in terms of controlling the pulse amplitude; it can generate a field strength from 0 to ∼230 kV/m between its plates, with a 34-kV charge voltage. The operating frequency can also be changed by altering the length of the transmission line. A circuit model is created for the setup to simulate the current waveform. The simulated and measured current waveforms are in agreement.
