非電磁屏蔽環(huán)境電源端傳導騷擾測試分析
發(fā)布時間:2018-12-11 11:17
【摘要】:比較了兩款不同電源產品在非電磁屏蔽環(huán)境和電磁屏蔽環(huán)境下的電源端傳導騷擾測試結果。結果表明,在3 MHz以下部分,兩種環(huán)境下的測試結果是一致的,但在3 MHz以上部分誤差較大。這說明電源端傳導騷擾測試的高頻部分受環(huán)境影響較大,如果需要得到準確的測量結果,測量需要在電磁屏蔽環(huán)境中進行。
[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.
