摘要
根据GB/T 18655-2010中的ALSE测试要求,通过测量线束上共模电流与共模电压,计算出线束的共模电磁辐射及低频电场辐射,得到线束时频域共模电流测量的辐射预测值及低频电场预测值,提出比在暗室内进行的天线测量方法更为简洁和节约的预评估方法,并分别通过仿真与试验进行了验证。
According to the ALSE test requirements in GB/T 18655-2010, by measuring the common mode current and common mode voltage on the wire harness, calculates the common mode electromagnetic radiation and the low frequency electric field radiation of the wire harness, and obtains the prediction value of the radiation and the prediction value of the low frequency electric field based on the common mode current measurement in the time and frequency domain of the wire harness, and proposes a more concise and economical method of evaluation than the antenna measurement method in the semi-anechoic chamber. The results are verified by simulation and test.
