System-level electrostatic discharge (ESD) noise due to electromagnetic fields radiating from an ESD generator were measured and analyzed in a solid-state drive (SSD) storage system. The field sources of an ESD generator were efficiently modeled from the measured tangential magnetic fields in front of a ESD generator. The extracted field sources were incorporated into a full-wave solver, and the fields inside the disk-array enclosure (DAE) were simulated and validated by comparing to measured fields. The field source models of the ESD generator were then also utilized to predict transient ESD-induced noise voltages in a simplified SSD. Finally, the coupling mechanism and the effects of the DAE geometry were investigated.

在固态驱动器（SSD）存储系统中，测量并分析了由于ESD发生器辐射的电磁场引起的系统级静电放电（ESD）噪声。ESD发生器的场源可以根据ESD发生器前面的切向磁场有效地建模。将提取的场源合并到全波求解器中，并通过与测量场进行比较来模拟和验证磁盘阵列机柜（DAE）内部的场。然后，还利用ESD发生器的场源模型在简化的SSD中预测ESD引起的瞬态噪声电压。最后，研究了耦合机理和DAE几何形状的影响。
