非电磁屏蔽环境电源端传导骚扰测试分析
发布时间：2018-12-11 11:17
【摘要】：比较了两款不同电源产品在非电磁屏蔽环境和电磁屏蔽环境下的电源端传导骚扰测试结果。结果表明,在3 MHz以下部分,两种环境下的测试结果是一致的,但在3 MHz以上部分误差较大。这说明电源端传导骚扰测试的高频部分受环境影响较大,如果需要得到准确的测量结果,测量需要在电磁屏蔽环境中进行。
[Abstract]:The test results of conducting disturbance at the end of two different power supply products in non-electromagnetic shielding environment and electromagnetic shielding environment are compared. The results show that under 3 MHz, the results of the two environments are the same, but the error is larger in the above 3 MHz. This indicates that the high frequency part of the test is greatly affected by the environment. If accurate measurement results are needed, the measurement should be carried out in the electromagnetic shielding environment.
