ESD模拟器全波模型的仿真与验证
资料介绍
针对静电放电ESD测试结果的可重复性较差的问题,在CST中建立了ESD模拟器全波模型,从仿真的角度探讨解决静电放电测试可重复性问题的方法。通过放电电流对全波模型进行初步验证;对印刷电路板PCB进行静电放电测试,得到了电磁场耦合电压和电磁场耦合规律;建立了抗扰度测试平台和PCB的全波模型,结合ESD模拟器全波模型对PCB静电放电测试进行仿真。全波模型的建立和有效性的验证表明,在电磁场耦合规律上,测量和仿真可以相互验证,为ESD模拟器全波模型的实际应用提供了参考。
Aiming at the problem of poor repeatability of ESD test results,a full-wave model of ESD simulator is established in CST. The method to solve the repeatability of ESD test is discussed from the simulation point of view. The full wave model is preliminarily verified by discharge current. ESD test is applied to the(printed circuit board)PCB to obtain the electromagnetic field coupling voltage and the electromagnetic field coupling law. The full wave models of the immunity test platform and the PCB are established,and combined with the full wave model of ESD simulator,the ESD test to PCB is simulated. The establishment and validation of full wave model shows that simulation and measurement can verify each other in electromagnetic coupling law,which provides a reference for the practical application of full wave model of ESD simulator.
