一个新的IEC61000-4-2标准ESD电流解析表达式

A new analytical expression of current waveform in standard IEC61000-4-2

分析了两个ESD标准电流波形表达式,并提出一个新的基于脉冲函数来描述ESD标准电流的解析表达式,该表达式符合最新的标准IEC61000-4-2,在零时刻的电流及其微分部为0,且波形与实际测量波形基本吻合。

According to the current waveform in standard IEC6100042, two analytical expressions of the standard current are analyzed and then a new one based on pulse function is proposed. The new expression is consistent with the new standard IEC6100042, in which bath the current and its derivative are zero at the zero moment, and the waveform basically is agreed with the measured one. 
